26.2 Introduction
26.2.1 Overview
This module implements an array of M N-input combinational muxes. All muxes share
the same N inputs in the same order, but each mux has its own independent select field.
The intended application of this module is to provide a flexible crossbar switch function
that allows any input (typically from external GPIO or internal module outputs) to be
connected to any output (typically to external GPIO or internal module inputs) under user
control. This is used to allow user configuration of data paths between internal modules
and between internal modules and GPIO.
A subset of the muxes can be configured to support edge detection and either interrupt or
DMA request generation based on detected signal edges on the mux output. This allows
signal transitions on the signals feeding the crossbar to trigger interrupts or initiate data
transfers via DMA into or out of other system modules.
