TMS320F2800137: Application issues of chips

May I ask how to configure CMPSS to use external pin inputs for PN? The official routines provided are for N-end using internal DAC. Can you provide a configuration method for a routine or syscfg? Thank you！

    Hi Tonyx,

    Thanks for your patience.

    To configure the negative pin of CMPSS module, you need to select "input driven by external pin" in negative input source section in SysConfig GUI.

    Then in "CMPSS MUX SELECT" section, you should assign your desired pin to the CMPHNMXSEL.

    Please let me know if you have any further questions.

    Regards,

    Hadi
