PIC18F2480/2580/4480/4580
23.6 Operation During Sleep
23.7 Effects of a Reset
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.
A device Reset forces all registers to their Reset state.
This forces the HLVD module to be turned off.
