21.6 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.

21.7 Effects of a Reset

A device Reset forces all registers to their Reset state.

This forces the HLVD module to be turned off.
