Operation During Sleep

The comparator, if enabled before entering Sleep mode,

remains active during Sleep. The additional current

consumed by the comparator is shown separately in the

Section 26.0 “Electrical

Characteristics”.

If the

comparator is not used to wake the device, power

consumption can be minimized while in Sleep mode by

turning off the comparator. Each comparator is turned off

by clearing the CxON bit of the CMxCON0 register.

A change to the comparator output can wake-up the

device from Sleep. To enable the comparator to wake

the device from Sleep, the CxIE bit of the PIE2 register

and the PEIE bit of the INTCON register must be set.

The instruction following the SLEEP instruction always

executes following a wake from Sleep. If the GIE bit of

the INTCON register is also set, the device will then

execute the Interrupt Service Routine.

20.6

Effects of a Reset

A device Reset forces the CMxCON0 and CM2CON1

registers to their Reset states. This forces both

comparators and the voltage references to their Off

states.
