describes UTFn fields.
Transmitter status. When written to, these bits control the meaning of UISRn[TxFIFO].
00 Inhibit transmitter FIFO status indication in UISRn.
01 Transmitter FIFO Š 25% empty
10 Transmitter FIFO Š 50% empty
11 Transmitter FIFO Š 75% empty
When read, these bits indicate the emptiness level of the FIFO.
00 Transmitter FIFO < 25% empty
01 Transmitter FIFO Š 25% empty
10 Transmitter FIFO Š 50% empty
11 Transmitter FIFO Š 75% empty
Transmitter FIFO full.
0 Transmitter FIFO is not full and can be loaded with a character.
1 Transmitter FIFO is full. Characters loaded into the transmitter FIFO when it is full are not transmitted.
Transmitter buffer data level. Indicates the number of bytes, between 0 and 24, stored in the transmitter FIFO.
