133X CompactFlash Card

Transcend Information Inc.



Execute Drive Diagnostic - 90h

When the diagnostic command is issued in a PCMCIA configuration mode, this command runs only on the

CompactFlash Storage Card that is addressed by the Drive/Head register. This is because PCMCIA card

interface does not allows for direct inter-drive communication (such as the ATA PDIAG and DASP signals). When

the diagnostic command is issued in the 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.

Diagnostic Codes are returned in the Error Register at the end of the command.



Erase Sector(s) - C0h

This command is used to pre-erase and condition data sectors in advance of a Write without Erase or Write

Multiple without Erase command. There is no data transfer associated with this command but a Write Fault error

status can occur.
