TMS320F280039C: configuring the Xbar module to make a GPIO generate Pulses "muxed as PWM pin"

Other Parts Discussed in Thread: SYSCONFIG

hello 

i read about the Xbar module but i still don't understand how to configure it for a Pin to generate a Pulse 

for a GPIO that can't be muxed directly into EPWM as seen in picture one


can i use the X bar module to do so indirectly for example mux the pin to outputxbar2 then configure it to generate a pulse ? 
if it is possible can you show me how to do it on Sysconfig ? 


thanks

    Hi Mahmoud,

    Are you trying to route an EPWM output to any GPIO? You can't do this with output xbar alone, however you can route an EPWM output to the input of the CLB, route it out of the CLB, and route the CLB output through an output xbar to almost any of the GPIOs.

    I've create the following .syscfg file to show an example of this:

    Let me know if you have any questions.
