Notes:
1.
The measurement condition is VCC = 1.8 V to 5.5 V and Topr =
20 to 85°C (N version) / 40 to 85°C (D version).
2.
The voltage detection level varies with detection targets. Select the level with the VCA24 bit in the VCA2 register.
3.
Time until the voltage monitor 2 interrupt request is generated after the voltage passes Vdet2.
4.
Necessary time until the voltage detection circuit operates after setting to 1 again after setting the VCA27 bit in the VCA2
register to 0.
Notes:
1.
The measurement condition is Topr =
20 to 85°C (N version) / 40 to 85°C (D version), unless otherwise specified.
2.
To use the power-on reset function, enable voltage monitor 0 reset by setting the LVDAS bit in the OFS register to 0.

Notes:
1. Vdet0 indicates the voltage detection level of the voltage detection 0 circuit. Refer to 6. Voltage Detection
Circuit of Hardware Manual (REJ09B0407) for details.
2. tw(por) indicates the duration the external power VCC must be held below the valid voltage (0.5 V) to enable
a power-on reset. When turning on the power after it falls with voltage monitor 0 reset disabled, maintain
tw(por) for 1 ms or more.
