| 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. [CD-ROM Commands With No Disc](/tests/cd-rom-no-disc-commands/) records the answer to each command once, across seven runs, and gives the same answers and the same Test 20h to 25h text. | The program has ten groups.
