Why SCK discontinuities when the SDK configures DSPI

Question asked by 张松 张 on Jul 10, 2018

I used the SDK 0.9.0 to configure the DSPI module, but the test found that the SOUT pin of the MPC5744 chip was pulled up after one byte of output, and that the SCK was also discontinuous; when I configured the DSPI, I chose a continuous mode, but the actual SCK waveforms were not continuous. I want to know why.

PS:When DSPIMasterSetDelay (SPI3s) function is not called, the transmission delay time between bytes is 0.56us. after calling the function, the byte transfer delay time is 2.5us.
