• External event pin (ADEVT) programmable as general-purpose I/O
7.2.2 Event Trigger Options
The ADC module supports three conversion groups: Event Group, Group1, and Group2. Each of these
three groups can be configured to be hardware event-triggered. In that case, the application can select
from among eight event sources to be the trigger for the conversions of a group.

NOTE
For ADEVT, N2HET trigger sources, the connection to the MibADC module trigger input is
made from the output side of the input buffer. This way, a trigger condition can be generated
either by configuring the function as output onto the pad, or by driving the function from an
external trigger source as input. If the mux controller module is used to select different
functionality instead of ADEVT or N2HET[x], care must be taken to disable these signals
from triggering conversions; there is no multiplexing on input connections.
NOTE
For the RTI compare 0 interrupt source, the connection is made directly from the output of
the RTI module. That is, the interrupt condition can be used as a trigger source even if the
actual interrupt is not signaled to the CPU.
