Recently I‘m writing the code for USART in interrupt mode,and I was refer to the examples of the SDK.But I can't find the Timing and Control aspect of the code。In other words, when send the last words to the FIFO,or other upper layer interrupt to react,how  much can I set the hold time to wait.

the second question:what the differences with this folders,and please told me if I want to write my code about USART with FIFO interrupt,which one can I refer to。

My MCU is LPC55S69,and my board is LPC55S69-EVK。
