If you look at page 112 of the data sheet which can be downloaded from Microchip,
You will see that to configure the A/D you write to register ADCON1. for example

ADCON1 = 0x80; /* 10 bit Right justified result, all analog inputs, Vdd as +ref, Vss -ref */

Then on page 111
To configure the conversion clock, select the input channel and turn on the A/D, you write to ADCON0, for example

ADCON0 = 0x81; /* Channel 0, A/D on, Conversion clock Fosc/32 */

These two registers are all you need to configure the A/D.

Then you set bit ADON in register ADCON0 to start the conversion.
ADON is cleared when the conversion is done.
