Hi team
My customer is using TMS570LS0914 with SPI. He wants to config the Clock polarity and clock phase of SPI (set to 01 mode).
But he tested the CLK waveform of spi and found that the CLK signal is high when it is not transmitting, and the waveform is a bit like the 11-mode waveform.
The following is the code and the CLK signal.
7288.TMS570.c
