Tool/software:

Hi, I am working on directly fetching ppg signals from AFE4490 using a dev board (without using AFE4490SPO2EVM) running on embedded linux via spi device "/dev/spidev0.0". Created drivers to control and receive data as per the AFE4400EVMFWSRC-v1.4 SDK's source code. What is the maximum, typical and minimum spi data transfer clock frequency? I couldn't see this detail in the source code.
