    Default MC9S12 Question Pin BKGD Broken

    hello I have a question, yesterday I was reading an MC9s12XET512MAG
    and I broke the BKGD pin. But the microcontroller does not work.


    I read that the pin is only necessary to perform the microcontroller programming


    Can the BKGD pin affect the microcontroller no longer working?


    regards

    Maybe because you not broke Pin 26 (BKGD) but pin 61 (PH3) and if you wired the othe wires incorrect you maybe killed the MCU.

    Thanks for the reply
    I just verified the microcontroller can work without the BKGD pin and the truck is able to start the engine, however the pin is used by the OBD2 interface to be able to enter to diagnose the modules. I have repaired the PIN.
    Thanks

    This Thread is SOLVED
