PIC18(L)F2X/4XK22
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.
