16.2
16.2.1
To enable the ADC module, the ADON bit of the
ADCON0 register must be set to a ‘ 1 ’. Setting the
GO/DONE bit of the ADCON0 register to a ‘ 1 ’ will start
the Analog-to-Digital conversion.
16.2.2
When the conversion is complete, the ADC module will:
• Clear the GO/DONE bit
• Set the ADIF Interrupt Flag bit
• Update the ADRESH and ADRESL registers with
16.2.3
If a conversion must be terminated before completion,
the GO/DONE bit can be cleared in software. The
ADRESH and ADRESL registers will be updated with
the partially complete Analog-to-Digital conversion
sample. Incomplete bits will match the last bit
converted.

ADC Operation
COMPLETION OF A CONVERSION
STARTING A CONVERSION
The GO/DONE bit should not be set in the
same instruction that turns on the ADC.
Refer to
sion Procedure”
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.
Section 16.2.6 “A/D Conver-
.
Preliminary
16.2.4
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.
16.2.5
The Special Event Trigger of the CCPx module allows
periodic ADC measurements without software inter-
vention. When this trigger occurs, the GO/DONE bit is
set by hardware and the Timer1 counter resets to zero.
TABLE 16-2:
Using the Special Event Trigger does not assure proper
ADC timing. It is the user’s responsibility to ensure that
the ADC timing requirements are met.
Refer to Section 20.0 “Capture/Compare/PWM
Modules” for more information.
