CMP_19	COUTVAL_01	Comparator Enabled to Output Valid	—	12	22	μs	Comparator module is configured before enabling it COMPCTRLx.SPEED = 0x0
CMP_19	COUTVAL_02	Comparator Enabled to Output Valid	—	1	2.6	μs	Comparator module is configured before enabling it COMPCTRLx.SPEED = 0x1
CMP_21	ACIREF	Comparator Internal Band Gap Voltage Reference	VR_9			V	VR_9: Refer to IVREF
CMP_23	CVREFRNG	Comparator Voltage Reference Input Range	(1)			V	See⁽¹⁾
CMP_25	FGCLK_AC_DIG	Analog comparator peripheral module digital clock freq	—	—	FCLK_48	MHz	See parameter FCLK_48 in Maximum Clock Frequency Table
CMP_26	FGCLK_AC_ANA	Analog comparator peripheral module analog clock freq	16	32	FCLK_49	KHz	See parameter FCLK_49 in Maximum Clock Frequency Table
Note: Comparator Reference voltage cannot exceed: (VIN(max) - VIOFF(max) - CMP_5(max) - 50 mV) ≥ 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.
