    Hi,

    so if i am using this function (The PCM1796 has a zero-detect function. When the PCM1796 detects the zero conditions as shown in Table 2, the
    PCM1796 sets ZEROL (pin 1) and ZEROR (pin 2) to HIGH.) and given condition then its working.

    ZeroL & R both are connected to microcontroller and gives high signal.

    this is only for 23ms and i am using it for 2-3 sec then what condition i put.
