36.10 Operation in Sleep Mode

The comparator module can operate during Sleep. A comparator interrupt will wake the device from Sleep. The CxIE bits of the respective PIE register must be set to enable comparator interrupts.

The comparator clock source is based on the Timer1 clock source. If the Timer1 clock source is either the system clock (F_OSC) or the instruction clock (F_OSC/4), Timer1 will not operate during Sleep, and synchronized comparator outputs will not operate.
