TDA4VM: Question about ESM input events

Shukai Ming

Part Number: TDA4VM

Hi experts,

  When I do not enable interrupt and errorpin of the error event in ESM configuration, Can I read the ESM_RAW_j register to determine whether the error event occurs?

Thanks,

Shukai

    Hi Shukai,

    The ESM can signal both low and high priority interrupts to a processor to deal with an event and/or manipulate an I/O error pin to signal an external hardware that an error has occurred.  

    So yes you could read/poll ESM_RAW_j, or could implement an interrupt handler to handle interrupts from the ESM.
