Example 11-1 shows an example that performs an A/D
conversion. The port pins are configured as analog
inputs. The analog reference V

channel.
EXAMPLE 11-1: PERFORMING AN A/D CONVERSION
;
; Ensure that the required sampling time for the
; selected input channel has lapsed. Then the
; conversion may be started.
; Wait for A/D completion and read ADRESH:ADRESL for result.
