17.1
When configuring and using the ADC the following
functions must be considered:
• Port configuration
• Channel selection
• ADC voltage reference selection
• ADC conversion clock source
• Interrupt control
• Results formatting
17.1.1
The ANSEL, ANSELH, TRISA, TRISB and TRISE reg-
isters all configure the A/D port pins. Any port pin
needed as an analog input should have its correspond-
ing ANSx bit set to disable the digital input buffer and
TRISx bit set to disable the digital output driver. If the
TRISx bit is cleared, the digital output level (V
V
The A/D operation is independent of the state of the
ANSx bits and the TRIS bits.
17.1.2
The CHS bits of the ADCON0 register determine which
channel is connected to the sample and hold circuit.
When changing channels, a delay is required before
starting the next conversion. Refer to Section 17.2
“ADC Operation” for more information.
17.1.3
The PVCFG and NVCFG bits of the ADCON1 register
provide independent control of the positive and
negative voltage references, respectively. The positive
voltage reference can be either V
external voltage
reference can be either V
source.
17.1.4
The ADCON2 register allows the user to select an
acquisition time that occurs each time the GO/DONE
bit is set.

module continues to sample the input for the selected
acquisition time, then automatically begins a conver-
sion. Since the acquisition time is programmed, there is
no need to wait for an acquisition time between select-
ing a channel and setting the GO/DONE bit.
Manual
ACQT<2:0> = 000. When the GO/DONE bit is set,
sampling is stopped and a conversion begins. The user
is responsible for ensuring the required acquisition time
has passed between selecting the desired input
channel and setting the GO/DONE bit. This option is
also the default Reset state of the ACQT<2:0> bits and
is compatible with devices that do not offer
programmable acquisition times.
In either case, when the conversion is completed, the
GO/DONE bit is cleared, the ADIF flag is set and the
A/D begins sampling the currently selected channel
again. When an acquisition time is programmed, there
is no indication of when the acquisition time ends and
the conversion begins.
17.1.5
The source of the conversion clock is software select-
able via the ADCS bits of the ADCON2 register. There
are seven possible clock options:
• F
• F
• F

The time to complete one bit conversion is defined as
T
as shown in Figure 17-3.
For correct conversion, the appropriate T
must be met. See A/D conversion requirements in
Table 27-9 for more information. Table 17-1 gives
examples of appropriate ADC clock selections.
