These channels are not implemented on PIC18F2XK20 devices.
Allow greater than 15 s acquisition time when measuring the Fixed Voltage Reference.
ADC REGISTER DEFINITIONS
Analog pin control is performed by the
ANSEL and ANSELH registers. For ANSEL
and ANSELH registers, see Register 10-2
and Register 10-3, respectively.
Unimplemented: Read as ‘0’
CHS<3:0>: Analog Channel Select bits
0000 = AN0
0001 = AN1
0010 = AN2
0011 = AN3
0100 = AN4
0101 = AN5
0110 = AN6
0111 = AN7
1000 = AN8
1001 = AN9
1010 = AN10
1011 = AN11
1100 = AN12
1101 = Reserved
1110 = Reserved
1111 = FVR (1.2 Volt Fixed Voltage 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
This bit is automatically cleared by hardware when the A/D conversion has completed.
