nRF5340 SPIS Max Speed

Hi Nordic .

  We are developing an application with nRF5340. In this application, we need to use the SPI Slave feature. According to the documentation, there isn't a clear indication of the maximum clock supported under SPI Slave mode, but it states that the minimum SCK time is 125ns, which would correlate to 8M.Based on our tests, when two nRF5340 communicate via 8M SPI, it works very well. However, when we test 16M SPI communication, errors in data content occur.

  Could you tell me what is the supported SPI frequency under the SPI Slave mode?
  Looking forward to your answer.
