Capstan motor forward/reverse control.
This pin determines the direction (forward
or reverse) of the capstan motor. (This
input has hysteresis characteristics.)
Selects the bias supply for all the capstan
motor circuits other than the FG
comparator. Setting this pin low cuts off
the bias supply. Thus it functions as the
standby mode control pin.
The output phase is locked by applying a
low to high trigger voltage (edge) to this
pin. This prevents the motor from turning
due to the application of an external load
in the motor stopped state.
Power supply used for the source side
pre-driver voltage and the coil waveform
detection comparator.
Power supply used for voltages other
than the motor voltage, the source side
pre-driver voltage, and the coil waveform
detection comparator.
Ground used for all systems other than
the output system.
