34.7 Comparator Negative Input Selection

The NCH bits direct an analog input pin and internal reference voltage or analog ground to the inverting input of the comparator:


NCH	Negative Input Sources
`111`	AVSS
`110`	FVR_Buffer2
`101`	CxNCH not connected
`100`	CxNCH not connected
`011`	CxIN3-
`010`	CxIN2-
`001`	CxIN1-
`000`	CxIN0-

Important: To use CxINy- pins as analog input, the appropriate bits must be set in the ANSEL register and the corresponding TRIS bits must also be set to disable the output drivers.
