title: CD-ROM Controller With No Disc
type: test
summary: Measures the CD-ROM controller's answers, reply times, FIFOs and registers with the lid open and no disc.
category: Hardware tests
info: Machine = SCPH-5501
info: Program = cdnodisc

## Overview

Every drive interrupt is polled: HINTMSK is 0 and CPU interrupts are off. Root counter 2 counts system clock cycles (33.8688 MHz) from each command write. Each group first sends Test 21h, Getstat and Getparam, so every result file records whether the lid was open.[^h]

The program has ten groups. They cover reply times, the Test 19h sub-functions, every command from 00h to 1Fh with 0 to 3 parameters, invalid command bytes, the registers in every bank, the parameter and response FIFOs, Init and ReadTOC, commands sent on top of commands, and the parameter FIFO past 16 bytes followed by Reset.[^h] The [CD-ROM registers](/hardware/cd-rom/registers/) and [CD-ROM commands](/hardware/cd-rom/commands/) pages describe the controller.

## Results

### Lid and Status

Test 21h answered 03h in every group: the door is open and the head is at its home position. Getstat answered 10h, which is the shell open bit.[^h]

### Reply Times

Getstat's INT3 came 19366 to 30488 cycles after the command write. That is 0.57 to 0.90 ms. BUSYSTS (HSTS bit 7) cleared about 2000 cycles before the interrupt in every sample.[^h]

Table: Reply times with no disc in cycles from the command

| Command | First interrupt | Range |
| --- | --- | --- |
| Getstat | INT3 | 19366 to 30488 |
| Getparam | INT3 | 26616 to 37932 |
| Nop with 1 parameter | INT5 | 22375 to 35763 |
| Command 1Fh | INT5 | 18815 to 29757 |
| Setloc | INT5 | 26936 to 37669 |
| Test 21h | INT3 | 22126 to 34975 |
| Test 22h | INT3 | 30913 to 47817 |

### Test Sub-functions

Test 20h answered the controller's date and version as 97h 01h 10h C2h. Test 22h answered the text "for U/C", Test 23h and 24h answered "CXD2545Q", and Test 25h answered "CXD1815Q".[^h]

Test 26h to 2Fh, 80h, F0h and FFh answered INT5 with error 10h. Test 20h with 2 or 4 parameters answered error 20h.[^h]

### Every Command

With no parameters, each command that needs a disc answered INT5 with stat 11h and error 80h. Commands 00h, 17h, 18h and 1Fh answered error 40h, which marks an invalid command. Init (0Ah) and ReadTOC (1Eh) answered INT3 and then INT2, and Getparam (0Fh) answered 10h 20h 00h 00h 00h.[^h]

A command given one parameter it does not take answered error 20h, which marks a wrong parameter count. An invalid command leaves its parameters in the FIFO: HSTS read 11h after it, where a valid command left 19h with the FIFO empty bit set.[^h]

The next command takes those parameters. Command 1Fh with the parameter 20h followed by a bare 19h answered the Test 20h version bytes.[^h]

### Init and ReadTOC

With the lid open, Init answered INT3 after 44952 to 49128 cycles and INT2 after 69992 to 74152 cycles. ReadTOC answered INT3 after 44922 to 52671 cycles and INT2 after 69962 to 77695 cycles.[^h]

A command written after Init's INT3 waits for Init to finish. Getstat sent right after Init answered only after Init's INT2, and a second Init sent right after the first answered INT3 and INT2 again after it.[^h]

An INT3 left unacknowledged holds back the next command. A Getstat written while Getparam's INT3 waited was answered only after the acknowledge, and the controller kept all five Getparam bytes for 100000 cycles.[^h]

### FIFOs

The parameter FIFO has 16 entries and its counter wraps at 32. HSTS showed the FIFO full after 16 writes and empty again after 32.[^h]

Table: HSTS before each parameter write

| Writes before | HSTS | Meaning |
| --- | --- | --- |
| 0 | 18h | Empty, ready |
| 1 to 15 | 10h | Ready |
| 16 | 00h | Full |
| 17 to 31 | 10h | Ready |
| 32 | 18h | Empty, ready |

A command after exactly 32 parameters saw none, so Getstat then succeeded. After 33 parameters, Setmode took one and succeeded.[^h]

The response FIFO is 16 bytes, and reads past the end wrap. Forty reads after Getstat gave 10h at reads 1, 17 and 33 and zeros between, and forty reads after Test 22h gave its 7 bytes every 16 reads.[^h]

### Registers

The index register reads back in HSTS bits 0 and 1. With no interrupt pending, 1F801803h read E0h in every bank. HINTMSK reads back its low 5 bits with bits 5 to 7 set.[^h]

An interrupt is acknowledged bit by bit. On a pending INT3, writing 01h left 02h and writing 02h then cleared it, and acknowledging bits 08h and 10h left INT3 pending.[^h]

### Reset

Command 1Ch answered INT3 10h. A Getstat written 400000 cycles later got no answer, and the Getparam after it answered normally. With 2 parameters Reset left them in the FIFO, so the next Getparam answered error 20h.[^reset]
