CPSCH<3:0>: Capacitive Sensing Channel Select bits
If CPSON = 0:
These bits are ignored. No channel is selected.
If CPSON = 1:
0000 = channel 0, (CPS0)
0001 = channel 1, (CPS1)
0010 = channel 2, (CPS2)
0011 = channel 3, (CPS3)
0100 = channel 4, (CPS4)
0101 = channel 5, (CPS5)
0110 = channel 6, (CPS6)
0111 = channel 7, (CPS7)
1000 = channel 8, (CPS8(1))
1001 = channel 9, (CPS9(1))
1010 = channel 10, (CPS10(1))
1011 = channel 11, (CPS11(1))
1100 = channel 12, (CPS12(1))

1110 = channel 14, (CPS14(1))
1111 = channel 15, (CPS15(1))
Note 1: These channels are not implemented on the PIC16F722/723/726/PIC16LF722/723/726.
2: This bit is not implemented on PIC16F722/723/726/PIC16LF722/723/726, Read as â0â
