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 46: "Diagnostic codes" on page 70 for the definition.
