18.5

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

Section 27.0 “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/GIEL bit of the INTCON register must be

set. The instruction following the SLEEP instruction

always executes following a wake from Sleep. If the

GIE/GIEH bit of the INTCON register is also set, the

device will then execute the Interrupt Service Routine.

18.6

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.
