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.

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.

Please refer to Section 9.1.5 “Interrupts” for more

information.

Conversion Starts

ADRES register is loaded,

GO/DONE bit is cleared,

ADIF bit is set,

Holding capacitor is connected to analog input

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.
