(4) Standby Mode

The setting of the standby mode allows the power supply in the device to be turned off forcibly.

The status of outputs from pins in standby is high impedance (H-bridge all OFF). In addition it is possible to

reduce the circuit current since the internal oscillation block stops.

When the stop operation is executed by the standby pin during normal operation, the motor is stopped by inertia

force.

When the normal status is reset, it takes several tens of µs to be activated.
