The source of the conversion clock is software
selectable via the ADCS bits of the ADCON2 register.
There are seven possible clock options:
• F
• F

The time to complete one bit conversion is defined as
T
as shown in
For correct conversion, the appropriate T
must be met. See A/D conversion requirements in
Table 27-22
examples of appropriate ADC clock selections.

The ADC module allows for the ability to generate an
interrupt upon completion of an Analog-to-Digital
Conversion. The ADC interrupt enable is the ADIE bit
in the PIE1 register and the interrupt priority is the ADIP
bit in the IPR1 register. The ADC interrupt flag is the
ADIF bit in the PIR1 register. The ADIF bit must be
cleared by software.
This interrupt can be generated while the device is
operating or while in Sleep. If the device is in Sleep, the
interrupt will wake-up the device. Upon waking from
Sleep, the next instruction following the SLEEP
instruction is always executed. If the user is attempting
to wake-up from Sleep and resume in-line code
execution, the global interrupt must be disabled. If the
global interrupt is enabled, execution will switch to the
Interrupt Service Routine.
