I am using mk22fn512 SPI1/SPI0 to send a series of data,Let SPI/SPI0 work in the loopback and continuous sck and continuous pcs mode.I found that when the SPI bus transmits data, each SOUT will have a certain delay after the completion of a single byte of data, which causes the slave device to be unable to determine the received data.
When I don't have a continuous sck mode, the waveform is below.
Continuous or discontinuous mode, SOUT does not have continuous output data. What is the reason?
Thanks and good luck！
