Comparator0 interrupts can be generated on both rising-edge and falling-edge output transitions. (For Interrupt
enable and priority control, see
upon a Comparator0 falling-edge interrupt, and the CP0RIF flag is set to logic 1 upon the Comparator0 rising-edge
interrupt. Once set, these bits remain set until cleared by software. The output state of Comparator0 can be obtained at
any time by reading the CP0OUT bit. Comparator0 is enabled by setting the CP0EN bit to logic 1, and is disabled by
clearing this bit to logic 0.
