ABSTRACT:
A sound controller has a signal pin for externally outputting the contents of bit 1 of a control register for controlling its operation mode as a power down signal POWERDOWN# for controlling a power supply to analog audio amplifiers. The power down signal POWERDOWN# output from the signal pin is sent to a power supply controller. The power supply controller switches supply/stop of a power supply voltage VCC2 to the analog audio amplifiers in response to the signal POWERDOWN#. With this control, the power down control of the analog audio amplifiers can be realized in accordance with the state of the sound controller.
