General System Control Information
5.7.2
The Crossbar Switch module provides a generic mechanism for making connections between on-chip peripherals as well as
between peripherals and pins. It provides a purely combinational path from input to output. The module groups 30 identical
multiplexes with 22 shared inputs. All Crossbar control registers that are used to select one of the 22 input signals to output are
write protected. Control of the write protection setting is in the SIM_PROT register.
In general, the crossbar module connects the Enhanced Flex PWM, ADC, Quad Timers, and comparators together, which allows
synchronization between PWM pulse generation and ADC sampling. In addition, several crossbar inputs and outputs are routed
to package pins. For example, the user can define an XB_INn pin as a PWM fault protection input that is routed to the PWM
module through the crossbar, increasing the flexibility of pin use and reducing the complexity of PCB layout.
