Bit 2: DisShadR (Disable Shadow Auto Response)
When the
DisShadR
bit is cleared, the
SShadow
bit is set, the
CDRV
bit is cleared, and the host
issues a command to the non-existent slave drive, the KS9245 responds to the shadow command
sequence automatically. When both
DisShadR
and
SShadow
bits are set, the auto shadow
response sequence is disabled
Bit 1: PcmdInt (ATAPI Packet Command host interrupt enable Mode)
When this bit is set and the drive is selected, a HINTRQ is generated when the KS9245 is ready to
receive the 12-byte command packet.
Bit 0: DisIORDY (Disable IO Ready Signal)
When this bit is set, the IORDY pin is disabled.
