(5) Reset circuit

The M61040 reset circuit is shown in figure 8. This circuit is composed of comparator, reference voltage section and

breeder resistor.

The reset output is Nch open drain structure so the reset delay time depends on external CR value.

The reset circuit monitors Vreg output to prevent microcomputer abnormal operation when VCC voltage goes down

abnormally.
