NOTE
For ADEVT trigger source, 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 ADEVT as an output function on to the pad (through the mux control), or by
driving the ADEVT signal from an external trigger source as input. If the mux control module
is used to select different functionality instead of the ADEVT signal, then care must be taken
to disable ADEVT from triggering conversions; there is no multiplexing on the input
connection.
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.
NOTE
For N2HETx trigger sources, the connection to the MibADC1 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.
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.
7.4.2.2 MibADC2 Event Trigger Hookup
Table 7-17 lists the event sources that can trigger the conversions for the MibADC2 groups.
