15.2.5 A/D CONVERSION PROCEDURE

This is an example procedure for using the ADC to

perform an Analog-to-Digital conversion:

1. Configure Port:

• Disable pin output driver (Refer to the TRIS

• Configure pin as analog (Refer to the ANSEL

2. Configure the ADC module:

• Select ADC conversion clock

• Select ADC input channel

• Turn on ADC module

3. Configure ADC interrupt (optional):

• Clear ADC interrupt flag

• Enable ADC interrupt

• Enable peripheral interrupt

• Enable global interrupt

(1)

4. Wait the required acquisition time

(2)

5. Start conversion by setting the GO/DONE

bit.

6. Wait for ADC conversion to complete by one of

the following:

• Polling the GO/DONE

bit

• Waiting for the ADC interrupt (interrupts

enabled)

7. Read ADC Result.

8. Clear the ADC interrupt flag (required if interrupt

is enabled).

Note 1: The global interrupt can be disabled if the

user is attempting to wake-up from Sleep

and resume in-line code execution.

2: Refer to Section 15.4 “A/D Acquisition

Requirements”.
