The SPI data is disconnected

Hi,all,

    I had a problem recently,The S32K324 SPI2 clock frequency 10MHz uses DMA to send how the interval between bytes is eliminated.One is the register configuration and the other is the timingiwEcAqNwbmcDAQTRA3UF0QGvBrC3lRJKGI5SVAV-io5SSEkAB9IIsKZwCAAJomltCgAL0gAAiPA.png_720x720q90.jpgiwEcAqNwbmcDAQTRBboF0QIYBrB0DGomrasoVwV-ioO8rMEAB9IIsKZwCAAJomltCgAL0gAA1D0.png_720x720q90.jpg

Hi,

SPI timing parameters are discussed in chapter 71.3.1.3 of the device RM. So you can refer to it and compare setting with your real signal. It would be great to add generated CS signal as well, to know full frame and a code used to send displayed frame. Could be also a delay is cause by SW overhead.
