Table 49 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 31 Diagnostic Codes” on Page 50 for the definition.
