Execute Drive Diagnostic
This command performs the internal diagnostic tests implemented by the CompactFlash Storage Card.
If in PCMCIA configuration this command runs only on the CompactFlash Storage Card which is addressed by the
Drive/Head register when the diagnostic command is issued. This is because PCMCIA card interface does not
allows for direct inter-drive communication (such as the ATA PDIAG and DASP signals). If in True IDE Mode the
Drive bit is ignored and the diagnostic command is executed by both the Master and the Slave with the Master
responding with status for both devices.
The Diagnostic codes shown in Table 39 are returned in the Error Register at the end of the command.
