摘要: A microcomputer includes a first switch coupled between a main power supply terminal and a power supply node, and a second switch coupled between an auxiliary power supply terminal and the power supply node. The microcomputer compares a voltage V1 of the main power supply terminal with a reference voltage VR1. When V1>VR1, the microcomputer turns on the first switch and turns off the second switch, and when V1
