Hi Stayhungry! 
 I would recommend that you read about the UART in the product specification , as you will find all the information you need there. 
Especially take a look at the reception section of the UART; 
 
 "The UART receiver chain implements a
FIFO capable of storing six incoming
RXD bytes before data is overwritten.
Bytes are extracted from this FIFO by
reading the RXD register." 
 
 You can read more about the FIFO library here . 
 
 "The FIFO library provides a simple
circular buffer implementation for
storing bytes." 
 
 So in short, the UART RX FIFO, is a buffer where the incoming RXD bytes are stored. 
 Best regards, 
Joakim.
