For AD2EVT trigger source, the connection to the MibADC2 module trigger input is made from the output side of the input buffer. This way, a trigger condition can be generated either by configuring AD2EVT as an output function on to the pad (through the mux control), or by driving the AD2EVT signal from an external trigger source as input. If the mux control module is used to select different functionality instead of the AD2EVT signal, then care must be taken to disable AD2EVT from triggering conversions; there is no multiplexing on the input connections.
If ePWM_B, ePWM_A2, ePWM_AB, N2HET2[1], N2HET2[5], N2HET2[13], N2HET1[11], N2HET1[17], or N2HET1[19] is used to trigger the ADC, the connection to the ADC is made directly from the N2HET or ePWM module outputs. As a result, the ADC can be triggered without having to enable the signal from being output on a device terminal.
For N2HETx trigger sources, the connection to the MibADC2 module trigger input is made from the input side of the output buffer (at the N2HETx module boundary). This way, a trigger condition can be generated even if the N2HETx signal is not selected to be output on the pad.
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.
