PIC16F716
REGISTER 8-2:
The ADRES register contains the result of the A/D
conversion. 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 8-1.
The value that is in the ADRES register is not modified
for any 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
conversion is started. The analog input channels must
have their corresponding TRIS bits selected as an
input. To determine acquisition time, see Section 8.1
“A/D
acquisition time has elapsed, the A/D conversion can
be started. The following steps should be followed for
doing an A/D conversion:

Configure the A/D module:
Configure A/D interrupt (if desired):
Wait the required acquisition time.
Start conversion:
Wait for A/D conversion to complete, by either:
OR
Read A/D Result register (ADRES), clear bit
ADIF if required.
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 next acquisition starts.
