10.1.6
The 10-bit A/D conversion result can be supplied in two
formats, left justified or right justified. The ADFM bit of
the ADCON0 register controls the output format.
Figure 10-4 shows the two output formats.
FIGURE 10-3:
10.2
10.2.1
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.
10.2.2
When the conversion is complete, the ADC module will:
• Clear the GO/DONE bit
• Set the ADIF flag bit
• Update the ADRESH:ADRESL registers with new
10.2.3
If a conversion must be terminated before completion,
the GO/DONE bit can be cleared in software. The
ADRESH:ADRESL registers will not be updated with
the partially complete Analog-to-Digital conversion
sample. Instead, the ADRESH:ADRESL register pair
will retain the value of the previous conversion. Addi-
tionally, a 2 T
sition can be initiated. Following this delay, an input
acquisition is automatically started on the selected
channel.

ADC Operation
RESULT FORMATTING
STARTING A CONVERSION
The GO/DONE bit should not be set in the
same instruction that turns on the ADC.
Refer to Section 10.2.6 “A/D Conver-
sion Procedure”.
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.

10.2.4
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
conversion to be aborted and the ADC module is
turned off, although the ADON bit remains set.
10.2.5
The ECCP Special Event Trigger allows periodic ADC
measurements without software intervention. When
this trigger occurs, the GO/DONE bit is set by hardware
and the Timer1 counter resets to zero.
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.
See Section 11.0 “Enhanced Capture/Compare/
PWM (With Auto-Shutdown and Dead Band)
Module (PIC12F615/617/HV615 only)” for more
information.
