22.6
Operation During Sleep
When enabled, the HLVD circuitry continues to operate
during Sleep. If the device voltage crosses the trip
point, the HLVDIF bit will be set and the device will
wake-up from Sleep. Device execution will continue
from the interrupt vector address if interrupts have
been globally enabled.
22.7
Effects of a Reset
A device Reset forces all registers to their Reset state.
This forces the HLVD module to be turned off.
