The start time for sampling can be controlled in soft-
ware by setting the SAMP control bit. The start of the
sampling time can also be controlled automatically by
the hardware. When the A/D converter operates in the
Auto-Sample mode, the SHA is reconnected to the
analog input pin at the end of the conversion in the
sample/convert sequence. The auto-sample function is
controlled by the ASAM control bit (AD1CON1<2>).
The conversion trigger source ends the sampling time
and begins an A/D conversion or a sample/convert
sequence. The conversion trigger source is selected by
the control bits SSRC<2:0> (AD1CON1<7:5>). The
conversion trigger can be taken from a variety of hard-
ware sources, or can be controlled manually in soft-
ware by clearing the SAMP control bit. One of the
conversion trigger sources is an auto-conversion. The
time between auto-conversions is set by a counter and
the ADC clock. The Auto-Sample mode and auto-con-
version trigger can be used together to provide endless
automatic conversions without software intervention.
An interrupt may be generated at the end of each sam-
ple sequence or multiple sample sequences as deter-
mined
(AD1CON2<5:2>). The number of sample sequences
between interrupts can vary between 1 and 16. The
user should note that the A/D conversion buffer holds
the results of a single conversion sequence. The next
sequence starts filling the buffer from the top even if the
number of samples in the previous sequence was less
than 16. The total number of conversion results
between interrupts is the SMPI value. The total number
of conversions between interrupts cannot exceed the
physical buffer length.

Operation of the ADC module is directed through bit
settings in the appropriate registers. The following
instructions summarize the actions and the settings.
Options and details for each configuration step are
provided in subsequent sections.
