The voltage detection circuit has the reset level detection circuit and the low voltage detection circuit. The
reset level detection circuit monitors the voltage applied to the V
reset level detection circuit detects V
to determine whether the individual circuit is enabled.
Use the reset level detection circuit for brown-out reset.
The low voltage detection circuit also monitors the voltage applied to the V
tion circuit use the VC13 bit in the VCR1 register to detect V
detection interrupt can be used in the voltage detection circuit.
