5.6.7 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.
