stm32h743iiWhen we set the OSPEEDRy[1:0] = 11 we have glitch spike (undershoot) on clock and data. it was improved when we set OSPEEDRy[1:0] = 01.In datasheet SPI interface characteristics page 307 saidOutput speed is set to OSPEEDRy[1:0] = 11.
Thank you very much. Do you have any document share with me that I can use for reference to close the case?or Do you have further other advice to fix the glitch spike?
