In SPI, I think SCK work after CS has low vol. But in my test with MK10FN1M0VLQ12 to slave isl78600 , SCK always work after one CS finish. I don't know why.
I'm not sure if Oscilloscope set wrong or not. I think it is SPIclock problem, but I adjust many times, and always wrong. Could you help me to test it or give me some advice, let me know how to solve it? Thank you!
