24.7
When a comparator is active and the device is placed
in Sleep mode, the comparator remains active and the
interrupt is functional, if enabled. This interrupt will
wake up the device from Sleep mode, when enabled.
Each operational comparator will consume additional
current.

To minimize power consumption while in Sleep mode,
turn off the comparators (CON = 0 ) before entering
Sleep. If the device wakes up from Sleep, the contents
of the CMxCON register are not affected.
24.8
A device Reset forces the CMxCON registers to their
Reset state. This forces both comparators and the
voltage reference to the OFF state.
