The conversion trigger will terminate acquisition and
start the requested conversions.
The SSRC<2:0> bits select the source of the conver-
sion trigger. The SSRC bits provide for up to 4 alternate
sources of conversion trigger.
When SSRC<2:0> = 000, the conversion trigger is
under software control. Clearing the SAMP bit will
cause the conversion trigger event after ~11 T
When SSRC<2:0> = 111 (Auto-Start mode), the con-
version trigger is under ADC clock control. The SAMC
bits select the number of ADC 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 1 clock cycle.
Other trigger sources can come from timer modules or
external interrupts.
19.5
Clearing the ADON bit during a conversion will abort
the current conversion and stop the sampling sequenc-
ing until the next sampling trigger. The ADCBUF will
not be updated with the partially completed ADC con-
version sample. That is, the ADCBUF will continue to
contain the value of the last completed conversion (or
the last value written to the ADCBUF register).
If the clearing of the ADON bit coincides with an auto-
start, the clearing has a higher priority and a new
conversion will not start.
19.6
The ADC conversion requires 14 T
the ADC conversion clock is software selected, using a
six-bit counter. There are 64 possible options for T

Since,
Sampling Time = Acquisition Time + Conversion Time
