NOTE
For N2HET1 trigger sources, the connection to the MibSPI1 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 MibSPI1 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 and 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 MibSPI1 transfers; there is no multiplexing on the input connections.
