5.6.2 Check Power Mode - 98h or E5h
If the CompactFlash Storage Card is in, going to, or recovering from the sleep mode, the CompactFlash Storage
Card sets BSY, sets the Sector Count Register to 00h, clears BSY and generates an interrupt.
If the CompactFlash Storage Card is in Idle mode, the CompactFlash Storage Card sets BSY, sets the Sector
Count Register to FFh, clears BSY and generates an interrupt.

5.6.3 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.
