5.5 Voltage Detection Circuit
Figure 5.5.1. Voltage Detection Circuit Block
0
C
The voltage detection circuit has circuits to monitor the input voltage at the V
voltage with respect to Vdet3, and Vdet4, respectively. Use the VC26 to VC27 bits in the VCR2 register to
select whether or not to enable these circuits.
Use the reset level detection circuit for hardware reset 2.
The voltage down detection circuit can be set to detect whether the input voltage is equal to or greater than
Vdet4 or less than Vdet4 by monitoring the VC13 bit in the VCR1 register. Furthermore, a voltage down
detection interrupt can be generated.
