These steps should be followed for doing an A/D
Conversion:
1.
Configure the A/D module:
• Configure analog pins/voltage reference and
digital I/O (ADCON1)
• Select A/D input channel (ADCON0)
• Select A/D conversion clock (ADCON0)
• Turn on A/D module (ADCON0)
2.
Configure A/D interrupt (if desired):
• Clear ADIF bit
• Set ADIE bit
• Set PEIE bit
• Set GIE bit

3.
Wait the required acquisition time.
4.
Start conversion:
• Set GO/DONE bit (ADCON0)
5.
Wait for A/D conversion to complete, by either:
• Polling for the GO/DONE bit to be cleared
(with interrupts enabled); OR
• Waiting for the A/D interrupt
6.
Read
(ADRESH:ADRESL), clear bit ADIF if required.
7.
For the next conversion, go to step 1 or step 2,
as required. The A/D conversion time per bit is
defined as T
required before the next acquisition starts.
