Analog Output Selector
Analog output selector block is shown in Figure 4. The command from microcomputer determines whether GND is
outputted to an analog terminal, or the voltage chosen in the battery voltage detection circuit is outputted.
At the time of GND output, since the battery voltage detection circuit stops, M61047FP goes into power save mode.
