Dear Member,

Could you please tell me why you need to connect the interrupt pin from ISD4002 to the microcontroller while you can read the EOM or OVF flag from the MISO register? Also, why are you connecting the RAC pin? I think it’s possible to keep it floating. Finally, is it required to set a frequency for the SCLK pin from the microcontroller or they will communicate by default without setting any clock?

All my questions are based on my understanding. If there is any thing wrong please inform me. I am sorry for disturbing you. Thanks again for your help.

Best regards,
Bakari
