Crossbar Switch (XBAR)
8.1
8.1.1 Overview
The crossbar switch module implements an array of 30 outputs and 22 inputs of
combinational digital multiplexes. All 30 multiplexes share the same 22 inputs in the
same order, but each multiplex has its own independent select field. The module's
registers control the select field for each multiplex.
This module is designed to provide a flexible crossbar switching matrix 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.
8.1.2 Features
The crossbar switch (XBAR) module's design includes these distinctive features:
Freescale Semiconductor
• Capability for generic inter-module connections between on-chip peripherals
• No synchronization delay between input and output
• 30 identical 22-input multiplexes with individual select fields
• Register write protection input signal
including ADCs, DAC, comparators, timers, PWM module, and GPIO pins
