Operation
When the A/D conversion is complete, the result is loaded into the ADRES register, the
GO/DONE bit (ADCON0<2>) is cleared, and A/D interrupt flag bit, ADIF, is set.
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 Subsection
Requirements.”
following steps should be followed for doing an A/D conversion:

time that the A/D module’s holding capacitor is connected to the external voltage level. Then
there is the conversion time of 10 T
two times is the sampling time. There is a minimum acquisition time to ensure that the holding
capacitor is charged to a level that will give the desired accuracy for the A/D conversion.
Figure 21-2: A/D Conversion Sequence
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 the ADIF bit
• Set the ADIE bit
• Set the GIE bit
Wait the required acquisition time.
Start conversion:
• Set the 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 the ADIF bit, 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
When A/D holding capacitor start to charge.
After A/D conversion, or new A/D channel is selected.
Acquisition Time
