5.3 Host Commands
C141-E203-01EN 5-45
(14) STANDBY (X’96’ or X’E2’)
Upon receipt of this command, the device enters the standby mode. If the device
has already spun down, the spin-down sequence is not implemented.
If the Sector Count field has a value other than "0," the APS timer is set when the
command is received. In this event, the device enters the command waiting state,
and the timer starts to count down. If a command is not received within the period
specified as the APS timer value, the device automatically enters Standby mode. If
the Sector Count field value is "0" the APS timer is disabled when the command is
received.
Under the standby mode, the spindle motor is stopped. Thus, when the command
involving a seek such as READ SECTOR(s) command is received, the device
processes the command after driving the spindle motor.
