2.7 Reset
2.7.3 Voltage drop detection circuit
The built-in voltage drop detection circuit is designed to detect a drop in voltage and to reset the microcomputer
if the supply voltage drops below a set value.
Figure 2.7.5 shows the voltage drop detection reset circuit, and Figure 2.7.6 shows the operation waveform
example of the voltage drop detection circuit.
