When the A/D conversion is complete, the result is
loaded into the ADRES register, the GO/DONE bit,
ADCON0<2>, is cleared, and the A/D interrupt flag bit,
ADIF, is set. The block diagram of the A/D module is
shown in Figure 9-1.
The value that is in the ADRES register is not modified
for a Power-on Reset. The ADRES register will contain
unknown data after a Power-on Reset.
After the A/D module has been configured as desired,
the selected channel must be acquired before the con-
version is started. The analog input channels must
have their corresponding TRIS bits selected as an
input. To determine acquisition time, see Section 9.1.
After this acquisition time has elapsed, the A/D conver-
sion can be started. The following steps should be fol-
lowed 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)
Configure A/D interrupt (if desired):
Clear ADIF bit
Set ADIE bit
Set GIE bit
Wait the required acquisition time.
Start conversion:
Set GO/DONE bit (ADCON0)
Wait for A/D conversion to complete, by either:
Polling for the GO/DONE bit to be cleared
OR
Waiting for the A/D interrupt
Read A/D Result register (ADRES), clear bit
ADIF if required.
For next conversion, go to step 1 or step 2 as
required. The A/D conversion time per bit is
defined as T
AD
. A minimum wait of 2T
AD
is
required before next acquisition starts.
