Forum Post: TMS320F28375D: How to continue supplying the SPI clock(SPICLK)

Part Number: TMS320F28375D Tool/software: Hi experts, Q: Is there a function to continue driving CLK even after sending command and address data to SPI Flash? After storing command and address data in the SpiaRegs.SPITXBUF register, we store 3 bytes of 0x00 data in the SpiaRegs.SPITXBUF register and supply CLK, but are there any other methods or functions? My customer is communicating with an external Flash using the SPI of the F28375D. When reading data stored in memory, CLK is supplied while command and address data is being sent from the DSP to the memory. However, once the transmission is completed, the CLK supply from the DSP stops. When the CLK supply stops, an event occurs where data cannot be received from the memory, and this is a problem. Best regards, O.H
