These channels are not implemented on PIC18F2XK20 devices.
Allow greater than 15 μs 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.
