Fujitsu MHM2100AT, MHM200AT, MHM215OAT, MHL2300AT manual Diagnostic code

Interface

When device 1 is not present:

•The device 0 posts only the results of its own self-diagnosis.

•The device 0 clears the BSY bit of the Status register, and generates an interrupt.

Table 5.6 lists the diagnostic code written in the Error register which is 8-bit code.

If the device 1 fails the self-diagnosis, the device 0 “ORs” X’80’ with its own status and sets that code to the Error register.

	Table 5.6 Diagnostic code
Code		Result of diagnostic
X’01’		No error detected.
X’03’		Data buffer compare error
X’05’		ROM sum check error
X’8x’		Failure of device 1

attention: The device responds normally to this command without executing internal diagnostic test.
