The voltage detection circuit consists of the reset level detection circuit and the low voltage detection circuit.
The reset level detection circuit monitors the voltage applied to the VCC1 pin. The microcomputer is reset if the reset
level detection circuit detects VCC1 is Vdet3 or below. This circuit is disabled when the microcomputer is in stop
mode.
The voltage detection circuit also monitors the voltage applied to the VCC1 pin. The low voltage detection signal is
generated when the low voltage detection circuit detects VCC1 is above or below Vdet4. This signal generates the low
voltage detection interrupt. The VC13 bit in the VCR1 register determines whether VCC1 is above or below Vdet4.
The voltage detection circuit is available when VCC1=5.0V.
Figure 6.1 shows a Voltage Detection Circuit Block.

The M16C/62PT do not use the voltage detection circuit.
However, the cold start-up/warm start-up determine function is available.
