The above applies to the following conditions.
NOTES:
• VCA27 bit in VCA2 register = 1 (voltage detection 2 circuit enabled)
• VW2C0 bit in VW2C register = 1 (enables voltage monitor 2 interrupt and voltage monitor 2 reset)
(Typ. 3.30V)
1. When the voltage monitor 1 reset is not used, set the power supply to VCC ≥ 2.7.
