20.4
The conversion trigger terminates acquisition and starts
the requested conversions.
The SSRC<2:0> bits select the source of the
conversion trigger.
The SSRC bits provide for up to five alternate sources
of conversion trigger.
When SSRC<2:0> = 000, the conversion trigger is
under software control. Clearing the SAMP bit causes
the conversion trigger.
When SSRC<2:0> = 111 (Auto-Start mode), the con-
version trigger is under A/D clock control. The SAMC
bits select the number of A/D clocks between the start
of acquisition and the start of conversion. This provides
the fastest conversion rates on multiple channels.
SAMC must always be at least one clock cycle.
Other trigger sources can come from timer modules,
motor control PWM module or external interrupts.
20.5
Clearing the ADON bit during a conversion aborts the
current conversion and stops the sampling sequencing.
The ADCBUFx is not updated with the partially com-
pleted A/D conversion sample. That is, the ADCBUFx
will continue to contain the value of the last completed
conversion (or the last value written to the ADCBUFx
register).
If the clearing of the ADON bit coincides with an
auto-start, the clearing has a higher priority.
After the A/D conversion is aborted, a 2 T
required before the next sampling may be started by
setting the SAMP bit.
If sequential sampling is specified, the A/D continues at
the next sample pulse, which corresponds with the next
channel converted. If simultaneous sampling is speci-
fied, the A/D continues with the next multichannel
group conversion sequence.

Note:
Programming the Start of the
Conversion Trigger
Aborting a Conversion
To operate the ADC at the maximum
specified conversion speed, the auto-
convert trigger option should be selected
(SSRC = 111) and the auto-sample
time
(SAMC = 00001). This configuration gives
a total conversion period (sample +
convert) of 13 T
The use of any other conversion trigger
