8.7 Idle (97h or E3h)
This command causes the Drive 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 (each count is 5ms) 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 (5ms) is different from the ATA specification. Table 43 defines the Byte sequence of the Idle
command.
