I3C Ctrl Transmit question

[hancheng]

Hello,
I am working with the STM32H503CBT6 and using the I3C Transmit_IT in Controller mode for communication.However, I encountered a problem, when I sent more than 260+ bytes, the data sent by the logic analyzer to capture, found that the captured data and I sent the data does not match, the following data will be the previous data directly off, suspected its FIFO overflow, but I do not know how to modify or how to find its error；
Thank you for your help!
