Dear Sir

 I use the init code from AFE4403EVM Firmware Source v2.2  ,but the ADC_RDY pin come only one time on my board .

I have debuged it , it only is generated after the reset ,then there is not generated always.

    Hello Banggeng,

    Did you check for the following?

    1. Probe the ADC_RDY signal on the oscilloscope and check if the ADC_RDY signal occurs at every PRF.

    2. Verify the AFE register configuration after the first ADC_RDY?

    3. Probe the RESETZ and AFE_PDNZ signal and check the status.
