NOTE
For AD2EVT, N2HET1 and GIOB trigger sources, 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 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 AD2EVT, 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.

The selection between the default MIBADC2 event trigger hook-up versus the alternate event trigger
hook-up is done by multiplexing control module register 30 bits 0 and 1.
If 30[0] = 1, then the default MibADC2 event trigger hook-up is used.
If 30[0] = 0 and 30[1] = 1, then the alternate MibADC2 event trigger hook-up is used.
NOTE
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 (via 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.
NOTE
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.
