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)
Idle
-
97h
or
E3h
This c ommand 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.

Idle Immediate - 95h or E1h
This c ommand causes the CompactFlash Storage Card to set BSY, enter the Idle mode, clear BSY and
generate an interrupt.
