AFE4405EVM: Communication with SPI

Part Number: AFE4405EVM

Hey Community,

I want to communicate with SPI to the AFE4405EVM.

So I need to change the I2C_SPI_SEL to RX_SUP.

But i cant find this PIN. Neither on my Hardware nor on my Software Register.

Thank you in anticipation

  • Hello,

    To switch to SPI interface, the AFE4405EVM would require hardware changes and also the board firmware should be updated.
    Do you have the AFE4405EVM schematics?
    Since this is an NDA device, I would like to take this conversation offline.
