bit 2:
bit 1:
bit 0:
Two A/D control registers are provided to control the conversion process. They are ADCON0 and
ADCON1. Both registers are readable and writable.
Register 24-1: ADCON0 Register
ADCS3:ADCS0: Analog Channel Select bits
0000 = AN0 input
0001 = AN1 input
0010 = AN2 input
0011 = AN3 input
0100 = Bandgap reference voltage input
0101 = Slope reference SREFHI input
0110 = Slope reference SREFLO input
0111 = AN11 input
1000 = AN12 input
1001 = AN13 input
1010 = AN4 input
1011 = AN5 input
1100 = AN6 input
1101 = AN7 input
1110 = AN14 input
1111 = AN15 input
Unimplemented: Read as '0'
AMUXOE: Analog MUX Output Enable
1 = Connect AMUX Output to AN0 pin (overrides TRIS setting)
0 = AN0 pin normal
ADRST: A/D Reset Control Bit
1 = Stop the A/D Timer, discharge CDAC capacitor
0 = Normal operation (A/D running)
ADZERO: A/D Zero Select Control
1 = Enable zeroing operation on AN1 and AN5
0 = Normal operation, sample AN1 and AN5 pins
