NOTES:
1. The measurement condition is T
2. This condition (external power VCC rise gradient) does not apply if V
3. To use the power-on reset function, enable voltage monitor 0 reset by setting the LVD0ON bit in the OFS register to 0, the
VW0C0 and VW0C6 bits in the VW0C register to 1 respectively, and the VCA25 bit in the VCA2 register to 1.

NOTES:
1. When using the voltage monitor 0 digital filter, ensure that the voltage is within the MCU operation voltage
range (2.2 V or above) during the sampling time.
2. The sampling clock can be selected. Refer to 6. Voltage Detection Circuit of Hardware Manual for details.
3. V
indicates the voltage detection level of the voltage detection 0 circuit. Refer to 6. Voltage Detection
