16.2.2
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
16.2.3
The discharge phase is used to initialize the value of
the capacitor array. The array is discharged after every
sample. This feature helps to optimize the unity-gain
amplifier, as the circuit always needs to charge the
capacitor array, rather than charge/discharge based on
previous measure values.
16.2.4
If a conversion must be terminated before completion,
the GO/DONE bit can be cleared by software. The
ADRESH:ADRESL registers will be updated with the
partially
sample. Unconverted bits will match the last bit
converted.
16.2.5
After the A/D conversion is completed or aborted, a
2 T
be started. After this wait, the currently selected
channel is reconnected to the charge holding capacitor
commencing the next acquisition.
16.2.6
The selection of the automatic acquisition time and A/D
conversion clock is determined in part by the clock
source and frequency while in a power-managed mode.
If the A/D is expected to operate while the device is in
a power-managed mode, the ACQT<2:0> and
ADCS<2:0> bits in ADCON2 should be updated in
accordance with the clock source to be used in that
mode. After entering the mode, an A/D acquisition or
conversion may be started. Once started, the device
should continue to be clocked by the same clock
source until the conversion has been completed.
If desired, the device may be placed into the
corresponding Idle mode during the conversion. If the
device clock frequency is less than 1 MHz, the A/D F
clock source should be selected.

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.

16.2.7
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.
16.2.8
The CCP1 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 or Timer3 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 13.3.4 “Special Event Trigger” for more
information.
