LPCOMP shares analog resources with SAADC. While it is possible to use the SAADC at the same time as the LPCOMP, selecting the same analog input pin for both modules is not supported.
Additionally, LPCOMP shares registers and other resources with other peripherals that have the same ID as the LPCOMP. See Peripherals with shared ID for more information.
The LPCOMP peripheral should not be disabled (by writing to the ENABLE register) before the peripheral has stopped. Failing to do so may result in unpredictable behavior.
