For ANSEL and ANSELH registers, see
Register 3-3 and Register 3-4, respectively.
ADCS<1:0>: A/D Conversion Clock Select bits
00 = F
01 = F
10 = F
11 = F
CHS<3:0>: Analog Channel Select bits
0000 = AN0

1110 = CV
1111 = Fixed Ref (0.6 volt fixed reference)
GO/DONE: A/D Conversion Status bit
1 = A/D conversion cycle in progress. Setting this bit starts an A/D conversion cycle.
0 = A/D conversion completed/not in progress
ADON: ADC Enable bit
1 = ADC is enabled
0 = ADC is disabled and consumes no operating current
ADCS0
R/W-0
This bit is automatically cleared by hardware when the A/D conversion has completed.
ADCON0: A/D CONTROL REGISTER 0
