--- title: SPU Registers and Envelope type: test summary: Reads the SPU's registers while it runs to measure key on and off, the ADSR envelope, volume sweeps, ENDX, IRQ9, capture and transfers. category: Hardware tests info: Machine = SCPH-5501 info: Program = spuenv --- ## Overview Sound cannot be recorded by the console, so every measurement reads a register: the ADSR level, the current volumes, ENDX, SPUSTAT, the repeat address, I_STAT, and the capture buffers through DMA4. Times are system clock cycles counted by root counter 2 from the write that starts the step. One SPU sample is 768 cycles.[^h] Nothing is audible during the test. The main volume stays 0000h, SPUCNT bit 14 stays 0, and every sample except the capture tone is silent. The program has 15 groups, and each group restores the registers it touched and keys off every voice before it returns.[^h] The [SPU](/hardware/spu/) page describes the unit, and the [SPU registers](/hardware/spu/registers/), [ADSR](/hardware/spu/adsr/) and [ADPCM](/hardware/spu/adpcm/) pages give the register layouts. See also: - [SPU Voice Flags and Interrupts](/tests/spu-voice-flags-interrupts/) - [SPU Envelope Grid and GPU Fill Timing](/tests/spu-envelope-grid-gpu-fill/) ## Results ### State at Entry As the program found the SPU, every voice had pitch 3FFFh and start address 0200h, and SPU_DELAY (1F801014h) read 200931E1h. SPUSTAT read 0005h sixteen times in a row.[^h] The unknown register 1DA0h reads AC00h most of the time and 0100h at other times: three of the first sixteen back-to-back reads gave 0100h, and two of sixteen reads 100000 cycles apart did the same.[^h] ### SPUCNT and SPUSTAT SPUSTAT bits 5 to 0 follow SPUCNT bits 5 to 0 after a delay. A change took between 61 and 765 cycles to appear, and eight repeats of the same 8000h to 8010h step took between 83 and 728 cycles.[^h] Setting the transfer mode bits 5 and 4 to 10b (DMA write) sets SPUSTAT bits 9, 7 and 5 together, so SPUSTAT reads 02A0h. Setting them to 11b (DMA read) shows 0030h first. About 1600 cycles later SPUSTAT reads 01B0h with bits 8 and 7 on.[^h] SPUCNT bits 6, 8 and 10 to 13 change nothing in SPUSTAT. SPUCNT reads back what was written. A write of FFFFh to SPUSTAT reads back FFFFh at once and returns to 0000h about 689 cycles later.[^h] ### Key On and Key Off KON took 3992 to 4582 cycles (five to six samples) to the first change of the ADSR level, whereas KOFF at 7FFFh changed the level within 39 to 69 cycles.[^h] KON on a voice that is already playing first sets the level to 0000h and starts the attack again. A KON while SPUCNT bit 15 is 0 produces no level change, and clearing bit 15 on a voice at 7FFFh drops its level to 3FFFh and then to 0000h.[^h] A value written to the ADSR level register reads back the written value. On a voice whose sustain never steps the value stays, and on a voice in a linear sustain the envelope continues from the written value.[^h] ### Attack Attack linear shift 0 with step 0 rises in steps of 3800h and reaches 7FFFh in three steps. Each step after the first adds the full step and the last step clamps at 7FFFh.[^h] Table: Attack time to 7FFFh in cycles from KON | Mode | Shift | Step | Cycles to 7FFFh | | --- | --- | --- | --- | | Linear | 0 | 0 | 6771 | | Linear | 2 | 0 | 11262 | | Linear | 5 | 0 | 60459 | | Linear | 8 | 0 | 453664 | | Linear | 10 | 0 | 1801523 | | Linear | 12 | 0 | 7193630 | | Exponential | 0 | 0 | 6715 | | Exponential | 4 | 0 | 51948 | | Exponential | 8 | 0 | 790079 | | Exponential | 12 | 0 | 12582662 | Each shift above 11 doubles the time between steps. An exponential attack rises at the linear rate until the level passes 6000h and then at a quarter of that rate. At shifts 8 and 12 it therefore took about 1.75 times as long as the linear attack of the same shift. Shift 31 with step 3 never changed the level.[^h] ### Decay and Sustain Level Decay stops at the first level at or below (SL + 1) x 800h: SL 0 stopped at 07FFh, SL 3 at 1FFFh and SL 7 at 3FFFh. With decay shift 0 the first decay step falls from 7FFFh straight to 3FFFh, so SL 7 to Eh all stopped at 3FFFh after one step. With SL Fh the level also fell one step and stopped: at 3FFFh with decay shift 0 and at 7FBFh with decay shift 8.[^h] ### Sustain Sustain linear increase shift 0 reached 7FFFh 8093 cycles after KON, two steps after the decay ended. Setting bit 29 of the ADSR word gave the same times as leaving it clear.[^h] A linear sustain decrease goes below zero: with shift 0 the level read FFFFh before it read 0000h. Every sustain with shift 31 and step 3 left the level at 3FFFh for two million cycles.[^h] ### Release Release begins within about 300 cycles of KOFF. Linear release shift 0 took the level from 7FFFh to 3FFFh in its first step and below zero to FFFFh in the next; the level then read 0000h from 1662 cycles after KOFF. Exponential release shift 0 halves the level at each step and ended at 10445 cycles.[^h] A KOFF during a slow attack releases from the level reached, so the level does not jump to 7FFFh first. After a release ends, the level stays at 0000h.[^h] ### Volume Sweep A sweep runs on a voice that has never been keyed on, so the volume registers sweep by themselves. A fixed volume of 1234h appears in the current volume register 1E08h as 2468h, which is twice the written value.[^h] Table: Volume sweep times of voice 2 left | Register | Start | Change | Cycles to the end | | --- | --- | --- | --- | | 8000h | 0000h | Linear increase, shift 0 | 2131 | | 8020h | 0000h | Linear increase, shift 8 | 449744 | | A020h | 7FFEh | Linear decrease, shift 8 | 393851 | | C020h | 0000h | Exponential increase, shift 8 | 785779 | | E000h | 7FFEh | Exponential decrease, shift 0 | 10876 | With the phase bit set (9020h), a linear increase from 2000h ran downward through zero and stopped at 8000h. With the all-ones rate 7Fh the volume did not move.[^h] ### ENDX ENDX bit 0 cleared between 795 and 2252 cycles after KON and set when the voice reached the block with the End flag. At pitch 1000h one block set ENDX after 16143 to 17602 cycles. Two blocks took about 37800 cycles and four blocks about 80800. ENDX can also be written: a write of 5555h reads back 5555h and then 0000h after 481 cycles as the voices update it.[^h] Pitches above 4000h run no faster than 4000h: four blocks set ENDX after 23953 to 23967 cycles at every pitch from 3FFFh to FFFFh. At pitch 0000h and 0001h the voice never reached its End flag.[^h] KON does not change the repeat address: right after KON it still read its old value. The loop start flag in the sample then set it; for a flag in block 0 this happened 1889 cycles after KON. A repeat address written while the voice is still in its first block is overwritten by the loop start flag, and one written later stays.[^h] ### IRQ9 A voice reading the IRQ address raises IRQ9: SPUSTAT bit 6 and I_STAT bit 9 both set, and the poll saw I_STAT about 200 cycles first. A voice stopped by End+Mute, and a voice released 100000 cycles before, still raised IRQ9 at its addresses, because such a voice keeps reading sound RAM. In the rows below the sample is four blocks at 4060h and plays at pitch 1000h.[^h] Table: IRQ9 time by IRQ address in cycles from KON | IRQ address | SPUSTAT bit 6 | I_STAT bit 9 | | --- | --- | --- | | 4060h | 1256 | 1057 | | 4061h | 6450 | 6251 | | 4062h | 318 | 116 | | 4064h | 40242 | 40043 | | 4065h | 49481 | 49216 | | 4066h | 318 | 116 | Manual writes raise IRQ9 when a written halfword reaches the IRQ address. Writes that began 8 bytes before it raised IRQ9 from the fourth halfword on. DMA writes over the IRQ address did not raise IRQ9 in any of four tries. DMA reads raised it, including a read that ended just before the IRQ address.[^h] ### Capture Buffers SPUSTAT bit 11 toggles every 196588 cycles, which is 256 samples, while transfer control is 0004h or 0008h. With transfer control 0000h, 0002h or 000Ch it never toggled.[^h] The capture buffers at the start of sound RAM raise IRQ9 when the IRQ address is set inside them. IRQ address 0000h to 01FFh hit once every 393000 cycles, and 0200h never hit.[^h] The voice 1 and voice 3 buffers hold the voice's output before its volume, so they carry the tone with the main and voice volumes at 0. The values with the ADSR level decayed to 3FFFh were the same as at 7FFFh. A released voice writes zeros.[^h] Noise mode at shift 15 changes every sample. Each lower noise shift halves the rate: 127 changes in 256 samples at shift 14, 32 at 12, 8 at 10 and 2 at 8.[^h] ### Transfers The Fifo is 32 halfwords deep: of 40 halfwords written in one block, the first 32 reached sound RAM. A second manual block with no new transfer address continues where the first ended.[^h] The transfer type in 1F801DACh changes what a manual write stores. Type 2 stores every halfword, type 3 every second one and type 4 every fourth. Type 5 stored only the seventh halfword, and types 0, 1, 6 and 7 stored only the last.[^h] Table: DMA read by transfer type | Type | Halfwords read | | --- | --- | | 3 | Each halfword followed by FFFFh or 0000h | | 4 | Each halfword four times | | 5 | Each halfword followed by 0000h, four times | ### Register Access Unknown registers 1DBCh, 1DBEh, 1DA0h and 1E60h to 1E7Fh read back what is written. The high halves of PMON, NON, EON and ENDX also read back written values. Halfword reads from 1E80h to 1FFEh all returned FFFFh, and the console did not hang.[^h] 32-bit stores to the ADSR low register lost the low half in 7 of 32 tries and never the high half. A 32-bit load and byte loads read the halves correctly. A byte store to an even SPU address writes the whole halfword from the register, and one to an odd address writes nothing.[^h] ## Runs ### Run 5501a-card-b on 27 September 2026 Raw output: [00RUN.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/00RUN.txt) · [01STA.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/01STA.txt) · [02CNT.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/02CNT.txt) · [03KON.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/03KON.txt) · [04ATK.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/04ATK.txt) · [05DEC.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/05DEC.txt) · [06SUS.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/06SUS.txt) · [07REL.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/07REL.txt) · [08SWP.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/08SWP.txt) · [09END.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/09END.txt) · [10IRQ.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/10IRQ.txt) · [11CAP.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/11CAP.txt) · [12VCP.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/12VCP.txt) · [13XFR.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/13XFR.txt) · [14REG.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s025/14REG.txt) · [15UNU.txt](/tests/raw/20260927T0000Z-5501a-card-b/spuenv/s026/15UNU.txt) 00RUN.txt: ``` ===== 00 RUN | BIOS 19951204 System ROM Version 3.0 11/18/96 A 15 tests A chain program, linked at 80100000 Saved on the card in slot 2, from image 1 COP0 at start: BPC 00000000 BDA 00000000 TAR BFC02BAC DCIC 00000000 BadVaddr 00000480 BDAM 00000000 BPCM 00000000 SR 40000000 Cause 00000020 EPC 8001D338 PRId 00000002 ``` 01STA.txt: ``` ===== 01 STA SPU STATE AT ENTRY | BIOS 19951204 System ROM Version 3.0 11/18/96 A BadVaddr as the group starts: 00000480 SPU registers as this program found them, nothing written first. 1DA8h, the transfer Fifo, is not read (shown ----). 1C00: 0000 0000 0400 0C28 8088 DFF1 0000 14C4 0000 0000 0407 0C28 8087 DFF1 0000 14C4 1C20: 0000 0000 0800 0C28 8088 DFF1 0000 14C4 0000 0000 080E 0C28 8087 DFF1 0000 14C4 1C40: 0000 0000 08FA 0200 8C7A DFED 0000 034C 0000 0000 090B 0200 8C7A DFED 0000 034C 1C60: 0000 0000 02AB 0C28 8088 DFF1 0000 14C4 0000 0000 02B0 0C28 8087 DFF1 0000 14C4 1C80: 0000 0000 0A14 0200 8C7A DFED 0000 034C 0000 0000 0A27 0200 8C7A DFED 0000 034C 1CA0: 0000 0000 0BFC 0200 8C7A DFED 0000 034C 0000 0000 0C12 0200 8C7A DFED 0000 034C 1CC0: 0000 0000 08FA 0200 8C7A DFED 0000 034C 0000 0000 090B 0200 8C7A DFED 0000 034C 1CE0: 0000 0000 0A14 0200 8C7A DFED 0000 034C 0000 0000 0A27 0200 8C7A DFED 0000 034C 1D00: 0000 0000 0BFC 0200 8C7A DFED 0000 034C 0000 0000 0C12 0200 8C7A DFED 0000 034C 1D20: 0000 0000 0556 0C28 8088 DFF1 0000 14C4 0000 0000 0560 0C28 8087 DFF1 0000 14C4 1D40: 0000 0000 0A14 0200 8C7A DFED 0000 034C 0000 0000 0A27 0200 8C7A DFED 0000 034C 1D60: 0000 0000 3FFF 0200 0000 0000 0000 0200 0000 0000 3FFF 0200 0000 0000 0000 0200 1D80: 0000 0000 0000 0000 0000 0000 FFFF FFFF 0000 0000 0000 0000 FFFF 003F FFFF 00FF 1DA0: AC00 E128 FFFE 0200 ---- C085 0004 0005 7FFF 7FFF 0000 0000 0000 0000 DFFF F7FF 1DC0: 033D 0231 7E00 5000 B400 B000 4C00 B000 6000 5400 1ED6 1A31 1D14 183B 1BC2 16B2 1DE0: 1A32 15EF 15EE 1055 1334 0F2D 11F6 0C5D 1056 0AE1 0AE0 07A2 0464 0232 8000 8000 1E00: 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 1E20: 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 1E40: 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 1E60: F5FF F3FF BFFF 38DF 74BB FFEE BFF7 FFEF FFFF FD7D 6EFF 33B3 FC7F FFFF BFFF 7D8F 1DA0h read 16 times in a row: A000 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 1DA0h read 16 times 100000 cycles apart: AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 AC00 A000 0100 AC00 AC00 SPUSTAT read 16 times 5000 cycles apart: 0005 0005 0005 0005 0005 0005 0005 0005 0005 0005 0005 0005 0005 0805 0805 0805 SPU_DELAY 1F801014h: 200931E1 Done. ``` 02CNT.txt: ``` ===== 02 CNT SPU SPUCNT TO STAT | BIOS 19951204 System ROM Version 3.0 11/18/96 A BadVaddr as the group starts: 00000480 SPUSTAT 5-0 is SPUCNT 5-0 applied a bit delayed (spx:726); bit 7 is like SPUCNT bit 5 (spx:721); DMA read sets 9 and 7 late (spx:727-729).
