Idle — 97h, E3h
When issued by the host, the device’s internal controller sets the BSY bit,
enters the Idle mode, clears the BSY bit, and generates an interrupt. If the
sector count is non-zero, it is interpreted as a timer count with each count
being 5ms, and the automatic power-down mode is enabled. If the sector
count is zero, the automatic power-down mode is disabled.
