2. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2
register to 0.
NOTES:
1. The measurement condition is V

3. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA26 bit in the VCA2
register to 0.
4. This parameter shows the voltage detection level when the power supply drops.
The voltage detection level when the power supply rises is higher than the voltage detection level when the power supply
drops by approximately 0.1 V.

NOTES:
1. The measurement condition is T
opr = −20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.
2. This condition (external power V
CC rise gradient) does not apply if VCC ≥ 1.0 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.
4. t
w(por1) indicates the duration the external power VCC must be held below the effective voltage (Vpor1) to enable a power on
reset. When turning on the power for the first time, maintain t
w(por1) for 30 s or more if −20°C ≤ Topr ≤ 85°C, maintain tw(por1) for
3,000 s or more if −40°C ≤ T
opr < −20°C.
