13.4
Example 13-2 shows how to perform an A/D conver-
sion. The RA pins are configured as analog inputs. The
analog reference (V
interrupt is enabled, and the A/D conversion clock is
F
(channel 0).

Ensure that the required sampling time for the selected input channel has elapsed.
Then the conversion may be started.
. The conversion is performed on the RA0 pin

Clearing the GO/DONE bit during a conversion will
abort the current conversion. The ADRES register will
NOT be updated with the partially completed A/D con-
version sample. That is, the ADRES register will con-
tinue to contain the value of the last completed
conversion (or the last value written to the ADRES reg-
ister). After the A/D conversion is aborted, a 2T
is required before the next acquisition is started. After
this 2T
