Receiver status. When written to, these bits control the meaning of UISRn[RxFIFO].
00 Inhibit receiver FIFO status indication in UISRn.
01 Receiver FIFO Š 25% full
10 Receiver FIFO Š 50% full
11 Receiver FIFO Š 75% full
When read, these bits indicate the emptiness level of the FIFO.
00 Receiver FIFO < 25% full
01 Receiver FIFO Š 25% full
10 Receiver FIFO Š 50% full
11 Receiver FIFO Š 75% full
Receiver FIFO full.
0 Receiver FIFO is not full and can be loaded with a character.
1 Receiver FIFO is full. Characters loaded from the receiver when the FIFO is full are lost.
This bit is identical to USRn[FFULL].
Receiver buffer data level. Indicates the number of bytes, between 0 and 24, stored in the receiver FIFO.
