22.4.10 Free-Running Sample
The
(SSRC = 111) in combination with the Automatic Sam-
pling Start mode (ASAM = 1), allows the ADC module
to schedule acquisition/conversion sequences with no
intervention by the user or other device resources. This
“Clocked” mode allows continuous data collection after
module initialization. See Example 22-3 for a code
example.
EXAMPLE 22-3:
22.4.11
In this case, one ADC input, AN0, will be acquired and
converted. The results are stored in the ADC1BUF buf-
fer. This process repeats 15 times until the buffer is full,
and then the module generates an interrupt. Then
entire process repeats.
With ALTS (AD1CON2<0>) clear, only the MUX A
inputs are active. The CH0SA (AD1CHS<19:16>) bits
and CH0NA (AD1CHS<23>) bit are specified (AN0-
VREF-) as the input to the sample/hold channel. Other
input selection bits are not used.
22.4.12
A typical setup might include all available analog input
channels to be sampled and converted. The CSCNA
(AD1CON2<10>) bit specifies scanning of the ADC

inputs. Other conditions are similar to the previous
example (see Section 22.4.11 “Sampling a Single
Channel Multiple Times”).
Initially, the AN0 input is acquired and converted. The
result is stored in the ADC1BUF buffer. Then the AN1
input is acquired and converted. This process of scan-
ning the inputs repeats 16 times until the buffer is full
and then the module generates an interrupt. Then the
entire process repeats.
22.4.12.1
To enable the dual 8-word buffers and alternating the
buffer fill, set the BUFM (AD1CON2<1>) bit. The BUFM
setting does not affect other operational parameters.
First, the conversion sequence starts filling the buffer at
ADC1BUF0 (buffer location 0 x 0). After the first inter-
rupt occurs, the buffer begins to fill at ADC1BUF8 (buf-
fer location 0 x 8). The BUFS (AD1CON2<7>) bit is
alternately set and cleared after each interrupt to show
which buffer is being filled. In this example, three ana-
log inputs are sampled and an interrupt occurs after
every third sample.
