600X CompactFlash Card

Transcend Information Inc.

V1.0

Idle - 97h or E3h

This command causes the CompactFlash Storage Card to set BSY, enter the Idle mode, clear BSY and
generate an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5
milliseconds and the automatic power down mode is enabled. If the sector count is zero, the automatic power
down mode is disabled. Note that this time base (5 msec) is different from the ATA specification.
