22.4.5
The CLRASAM bit provides a method to terminate
auto-sample after the first sequence is completed. Set-
ting the CLRASAM and starting an auto-sample
sequence will cause the A/D converter to complete one
auto-sample sequence (the number of samples as
defined by SMPI<3:0> (AD1CON2<5:2>)). Hardware
will clear ASAM (AD1CON1<2>) and set the interrupt
flag. This will stop the sampling process to allow
inspection of the result buffer without results being
overwritten
sequence. The CLRASAM must be cleared by software
to disable this mode.

Disabling interrupts or masking the ADC
interrupt has no effect on the operation

Preliminary
22.4.6
The following configuration examples show the ADC
operation in different sampling and buffering configura-
tions. In each example, setting the ASAM bit starts
automatic sampling. A conversion trigger ends sam-
pling and starts conversion.
22.4.7
When SSRC<2:0> = 000, the conversion trigger is
under software control. Clearing the SAMP bit
(AD1CON1<1>) starts the conversion sequence. See
Example 22-1 for sample code to manually control the
sampling of a single channel.
