ADSP-BF538 SPORT - External Clock

If Serial ports are configured to use external clock, what happens if we cut off external clock signal ?
Does DSP provide any kind of notification that external clock signal is not active like interrupt or status bit updates.

Thank You

  • Hi,
    There is no register bit or interrupt to notify that external clock signal is not active. Unless the clock is enable the data will not transfer or receive in the SPORT.
    Can you please let us know what is the exact failure you are facing? If your are struck in providing the external clock to the SPORT, please refer "Audio_test.c" available in the below mentioned directory.
