I'm using the STM32H503RB Eval board to create an I3C target, but I'm encountering issues with implementing the TX FIFO. From what I understand, the TX FIFO needs to be preloaded, which I've already done. However, now I'm facing an issue where the ninth bit is missing. My question is: what is the correct procedure for implementing the TXFNF (TX FIFO Not Full) flag in my code? Please note that I'm working with interrupt-based functions.
