Notes:
1. The measurement condition is VCC = 2.7 V to 5.5 V and Topr = −40 to 85°C (J version) / −40 to 125°C (K version).
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.
3. Time until the voltage monitor 0 reset is generated after the voltage passes Vdet0.
