PIC18F87K22 FAMILY
After the A/D module has been configured as desired,
the selected channel must be acquired before the
conversion can start. The analog input channels must
have their corresponding TRIS bits selected as an
input. To determine acquisition time, see Section 23.3
“A/D Acquisition Requirements” . After this acquisi-
tion time has elapsed, the A/D conversion can be
started. An acquisition time can be programmed to
occur between setting the GO/DONE bit and the actual
start of the conversion.
To do an A/D conversion, follow these steps:
1.
FIGURE 23-5:
DS39960B-page 358
Configure the A/D module:
• Configure the required ADC pins as analog
• Set the voltage reference (ADCON1)
• Select the A/D positive and negative input
• Select the A/D acquisition time (ADCON2)
• Select the A/D conversion clock (ADCON2)
• Turn on the A/D module (ADCON0)

Configure the A/D interrupt (if desired):
• Clear the ADIF bit (PIR1<6>)
• Set the ADIE bit (PIE1<6>)
• Set the GIE bit (INTCON<7>)
Wait the required acquisition time (if required).
Start the conversion:
• Set the GO/DONE bit (ADCON0<1>)
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 registers (ADRESH:ADRESL)
and, if required, clear bit, ADIF.
For the next conversion, begin with step 1 or 2,
as required.
The A/D conversion time per bit is defined as T
Before the next acquisition starts, a minimum Wait
of 2 T
