Thank you for answering my previous questions, now, I am going very well with FPGA-based controller design.
with one question, I think the interrupt mode allow RS232 send/
receive data more than 16 bytes, why I can not do it, I set the
sendbuffer to 18 bytes, but still just 16bytes sent out.
Any other setting?

I've never used the UartLite, but I believe it has a 16 character xmit buffer (fifo). I suspect
you're sending data to the buffer to fast and characters beyond the 1st 16 are getting dropped.
If you are using interrupts, you are probably not paying proper attention to the fifo full condition.
