Programmable interrupt threshold counter is available for each group
Programmable magnitude threshold interrupt for each group for any one channel
Option to read either 8-bit, 10-bit or 12-bit values from memory regions
Single or continuous conversion modes
Embedded self-test
Embedded calibration logic
Enhanced power-down mode
Optional feature to automatically power down ADC core when no conversion is in progress
External event pin (ADEVT) programmable as general-purpose I/O
5.2.2
Event Trigger Options
The ADC module supports 3 conversion groups: Event Group, Group1 and Group2. Each of these 3
groups can be configured to be hardware event-triggered. In that case, the application can select from
among 8 event sources to be the trigger for a group's conversions.

NOTE
For ADEVT, N2HET1 and GIOB trigger sources, the connection to the MibADC1 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 (via the mux
control), or by driving the function from an external trigger source as input. If the mux control
module is used to select different functionality instead of the ADEVT, N2HET1[x] or GIOB[x]
signals, then care must be taken to disable these signals from triggering conversions; there
is no multiplexing on the 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.
