Power switch and reset

Applicable receivers: BD970 | BD982 | BD990 | BD992 | BD992-INS

Power switch

The integrator may choose to power on or power off the unit. If a 3.3 V level signal is applied to pin 3, Power_Off pin, the unit will disconnect VCC. The system integrator must ensure that other TTL level pins remain unpowered when Power_Off is asserted. Powering TTL-level pins while the unit is powered off will cause excessive leakage current to be sinked by the unit.

The integrator may choose to always have the unit powered on. This is accomplished by leaving the Power_Off pin floating or grounded.

Reset switch

Driving Reset_IN_L, Pin 12, low will cause the unit to reset. The unit will remain reset at least 140 mS after the Reset_IN_L is deasserted. The unit remains powered while in reset.
