    Hi Shukai,

    The documentation defines the esmErroConfig field as below:

    In regards to the the API ESM_esmInitConfig_WKUP.  The TDA4VM device has 3 domains, WKUP, MCU, MAIN.   This particular API call will be used as initialization, prior to a self test to verify the ESM functionality for the WKUP domain.

    Regards,

    Hi KB,

      Thanks for your reply.

      Could you please tell me what does "Configuration interrupt" ESM outputs mean? 

      "High and Low interrupt" is good to understand.

    Thanks,

    Shukai

    Hi,

    The TDA4VM Technical Reference Manual shows the below registers for ESM.  The "configuration interrupt" and high / low interrupt are referring to the registers there, where:

    • "Configuration interrupt" - refers to the Config Error Raw/Status/Enable registers
    • " High and Low Interrupt" - refers to the ESM_LO_PRI and EMS_HI_PRI / ESM_LO / ESM_HI registers.

    Regards,
