This command causes the ATA Flash Disk Controller 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 also enabled, the timer count is set to 3, with each count being 5 ms.
Note that this time base (5 msec) is different from the ATA specification.
This command causes the ATA Flash Disk Controller to set BSY, enter the Idle mode, clear BSY and
generate an interrupt.
