Table 77 Execute Device Diagnostic Command (90h)
The Execute Device Diagnostic command performs the internal diagnostic tests implemented by the device. The
results of the test are stored in the Error Register.
The normal Error Register bit definitions do not apply to this command. Instead, the register contains a
diagnostic code. See Table 36 Diagnostic Codes‖ on the page 55 for its definition.
