    Hi Dhanush,

    QUAD SSI is meant to be used for connecting to SPI Flash Memories. There are many vendors for the same and each having their own subtlety. You need to be more precise as to what you want to do with Quad SSI.

    Hello Dhanush,

    The Initialization code for SSI in Quad Mode is same as other modes. To communicate with the SPI Flash you would need to use the SSICR1 register to construct the packet for SPI Flash.

    If you can start with a sample code of your own, i can help rectify and construct the same.
