TMS320F280039C: TMS320F280039C Trip Zone via XBAR

Part Number: TMS320F280039C

Hi,

Please advise which Pins on the 64 pin device can be mapped to the TZ1 TZ2 and TZ2 registers.  It is not clear in the technical information I am reading.

Thank you,

William

    Hi William,

    Refer to this figure in the crossbar chapter:

    TZ1-3 and TZ6 are directly routed to the input XBAR.

    Thank you,

    Luke

    Hi Luke,

    I saw that but my confusion is determining which GPIO pins these input XBARS map out to?  What pins on the 64-pin TMS320F280039C device are mapped to the Trip Zone signals? Where do I find that information?  For example, if I want to configure a GPIO pin to trip a TZ1 fault of the ePWM module, what pin would I wire that fault signal to on the 64-pin device of the TMS320F280039C?

    Thank you,

    William

    Hi William,

    Each Input XBAR can connect to any of the GPIOs. This is determined by the INPUTxSELECT registers in the Cross-bar chapter. In the case of TZ1 you would configure INPUT1SELECT.
