A/D Channel Selects. Refer to Table 8-1.
Unimplemented. Read as ‘0’.
Analog Mux Output Enable
1 = Connect AMUX Output to RA0/AN0 pin (overrides TRISA<0> setting)
0 = RA0/AN0 pin normal
A/D Reset Control Bit
1 = Stop the A/D Timer, discharge CDAC capacitor
0 = Normal operation (A/D running)
A/D Zero Select Control. (Refer to Section 9.2)
1 = Enable zeroing operation on RA1/AN1 and RD5/AN5
0 = Normal operation (sample RA1/AN1 and RD5/AN5 pins)
