UART Modules
16.3.4
The UART clock-select registers (UCSRn) select an external clock on the URT_CLK input (divided by 1
or 16) or a prescaled CLKIN as the clocking source for the transmitter and receiver. See
“Transmitter/Receiver Clock
CLKIN for both, set UCSRn to 0xDD.

FIFO full. This bit is equivalent to URF[FULL].
0 The FIFO is not full but may hold unread characters.
1 A character was received and the receiver FIFO is now full. Any characters received when the FIFO is full
0 The CPU has read the receiver buffer and no characters remain in the FIFO after this read.
1 One or more characters were received and are waiting in the receiver buffer FIFO.
