PIC10(L)F320/322
15.1.5
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.

Note:
The ADIF bit is set at the completion of
every conversion, regardless of whether
or not the ADC interrupt is enabled.
INTERRUPTS
Preliminary
15.2
15.2.1
To enable the ADC module, the ADON bit of the
ADCON register must be set to a ‘1’. Setting the GO/
DONE bit of the ADCON register to a ‘1’ will start the
Analog-to-Digital conversion.
15.2.2
When the conversion is complete, the ADC module will:
• Clear the GO/DONE bit
• Set the ADIF Interrupt Flag bit
• Update the ADRES register with new conversion
15.2.3
If a conversion must be terminated before completion,
the GO/DONE bit can be cleared in software. The
ADRES register will be updated with the partially com-
plete Analog-to-Digital conversion sample. Incomplete
bits will match the last bit converted.
15.2.4
The ADC module can operate during Sleep. This
requires the ADC clock source to be set to the F
option. When the F
ADC waits one additional instruction before starting the
conversion. This allows the SLEEP instruction to be
executed, which can reduce system noise during the
conversion. If the ADC interrupt is enabled, the device
will wake-up from Sleep when the conversion
completes. If the ADC interrupt is disabled, the ADC
module is turned off after the conversion completes,
although the ADON bit remains set.
When the ADC clock source is something other than
F
sion to be aborted and the ADC module is turned off,
although the ADON bit remains set.

STARTING A CONVERSION
The GO/DONE bit should not be set in the
same instruction that turns on the ADC.

COMPLETION OF A CONVERSION
TERMINATING A CONVERSION
A device Reset forces all registers to their
Reset state. Thus, the ADC module is
turned off and any pending conversion is
terminated.
