5.3 Host Commands
C141-E104-03EN
5-61
(27) SLEEP (X’99’ or X’E6’)
This command is the only way to make the device enter the sleep mode.
Upon receipt of this command, the device sets the BSY bit of the Status register
and enters the sleep mode. The device then clears the BSY bit and generates an
interrupt. The device generates an interrupt even if the device has not fully
entered the sleep mode.
In the sleep mode, the spindle motor is stopped and the ATA interface section is
inactive. All I/O register outputs are in high-impedance state.
The only way to release the device from sleep mode is to execute a software or
hardware reset.
