HYSTSEL
Select hysteresis level. The hysteresis levels can vary, please see the electrical characteristics for the device for more information.
GPIOINV
Set this bit to 1 to invert the comparator alternate function output to GPIO.
INACTVAL
The value of this bit is used as the comparator output when the comparator is inactive.
MUXEN
Enable Input Mux. Setting the EN bit will also enable the input mux.
