15.1.5 INTERRUPTS

The ADC module allows for the ability to generate an

interrupt upon completion of an Analog-to-Digital

conversion. The ADC Interrupt Flag is the ADIF bit in

the PIR1 register. The ADC Interrupt Enable is the

ADIE bit in the PIE1 register. The ADIF bit must be

cleared in software.

Note 1: The ADIF bit is set at the completion of

every conversion, regardless of whether

or not the ADC interrupt is enabled.

2: The ADC operates during Sleep only

when the FRC oscillator is selected.

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 instruc-

tion is always executed. If the user is attempting to

wake-up from Sleep and resume in-line code execu-

tion, the GIE and PEIE bits of the INTCON register

must be disabled. If the GIE and PEIE bits of the

INTCON register are enabled, execution will switch to

the Interrupt Service Routine.

15.1.6 RESULT FORMATTING

The 10-bit A/D conversion result can be supplied in two

formats, left justified or right justified. The ADFM bit of

the ADCON1 register controls the output format.

Figure 15-3 shows the two output formats.
