7.14 FIFO ready register
The FIFO ready register provides real-time status of the transmit and receive FIFOs
of both channels.
The FIFO Rdy register is a read-only register that can be accessed when any of the
two UARTs is selected CSA - CSD = 0, MCR[2] (FIFO Rdy Enable) is a logic 1, and
loop-back is disabled. The address is 111.

Description
FIFO Rdy[7:4]
0 = There are less than a RX trigger level number of characters
in the RX FIFO.
1 = The RX FIFO has more than a RX trigger level number of
characters available for reading
or
a time-out condition has
occurred.
FIFO Rdy[3:0]
0 = There are less than a TX trigger level number of spaces
available in the TX FIFO.
1 = There are at least a TX trigger level number of spaces
available in the TX FIFO.
