Idle–97H, E3H
This command causes the card to set BSY, enter the Idle (Read) 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
: This time base (5 msec) is different from the ATA specification.
