Fujitsu MCJ3230AP manual When device 1 is connected, Self-diagnosis detailed code

Host Interface

When the ODD receives this command, it responds to the command regardless of the DEV bit value; this means that the drive is unit 0 or 1.

When the ODD is device 0 (master), its response after the command is received depends on whether device 1 (slave) is connected.

When no device 1 is connected

The ODD sets 01h in the Error register and terminates the command.

When device 1 is connected

The ODD monitors the PDIAG- signal sent from device 1 for six seconds. If device 1 asserts the PDIAG- signal within this time, the ODD recognizes that the device 1 self-diagnostic test ends successfully. Otherwise, the ODD recognizes that the device 1 self-diagnostic test ended abnormally and the ODD makes OR- operation to its self-diagnostics results of unit 0 (Device 0) with 80h and sets it in the Error register. If device 1 ends abnormally, the ODD sets the CHECK bit of the Status register.

When the ODD is device 1

The ODD asserts the PDIAG- signal within five seconds. It sets 01h in the Error register and ends the command.
