CMP_19	COUTVAL_02	Comparator Enabled to Output Valid	—	—	3.8	μs	Comparator module is configured before enabling it COMPCTRLx.SPEED = 0x3
CMP_21	ACIREF	Comparator Internal Band Gap Voltage Reference	VR_9 to VR_27			V	VR_9 to VR_27 : Refer to IVREF
CMP_23	CVREFRNG	Comparator Voltage Reference Input Range⁽¹⁾	(1)	—	AVDD - 1V or⁽¹⁾, whichever is lower	V	(Note 1)

Note: Comparator Reference voltage cannot exceed: (VIN(max) - VIOFF(max) - CMP_5(max) - 50mV) ≥CMP_23 ≥ (VIN(min) + abs(VIOFF(min)) + CMP_5(max) + 50 mV). TRESPss_XX is measured from VIN transition to CMPx output toggle. It takes into account only analog propagation delay.
