Example 8-1 shows the configuration of the PLVD mod-
ule and a sample polling routine to monitor for low volt-
age conditions.

8.3
When enabled, the PLVD circuitry continues to operate
during SLEEP. If the device voltage crosses the trip
point, the LVDIF bit is set and the device awakens from
SLEEP. Device execution continues from the interrupt
vector address, if interrupts have been globally
enabled.

A device RESET forces all registers to their RESET
state. This forces the PLVD module to be disabled.
