NOTE

For N2HET1 trigger sources, the connection to the MibSPI3 module trigger input is made

from the input side of the output buffer (at the N2HET1 module boundary). This way, a

trigger condition can be generated even if the N2HET1 signal is not selected to be output on

the pad.

NOTE

For GIOx trigger sources, the connection to the MibSPI3 module trigger input is made from

the output side of the input buffer. This way, a trigger condition can be generated either by

selecting the GIOx pin as an output pin plus selecting the pin to be a GIOx pin, or by driving

the GIOx pin from an external trigger source. If the mux control module is used to select

different functionality instead of the GIOx signal, then care must be taken to disable GIOx

from triggering MibSPI3 transfers; there is no multiplexing on the input connections.
