I want to receive 255 byte via UART on TM4C123 MCU. I connect the kit with PC via Com port USB debugger.

How can I do it?

Start with the TivaWare examples

Along w/TivaWare examples - tall mountains (often) are best climbed by practicing on shorter ones.

KISS dictates that you start w/single byte - then 10 - as you extend beyond 16 bytes your skills will be challenged. Starting from the number you note will (most likely) toss you from the mountain...

I was received 14 byte, but the FIFO's capacitor only 16 byte. I don't have any idea to solve that problem.

When your FIFO "fills" to a certain point - that event generates a "signal" - does it not? Might it make sense to (then) empty the FIFO - storing the FIFO's contents - and continue? Good read/review of the MCU manual's UART section should prove useful...
