The receiver writes data to the bottom of the RHR when it finishes receiving and decoding the data bits. If
the RHR is full when the receiver attempts to write data to it, a data overrun occurs. Any read operation to
an empty RHR is invalid.
The empty and full status of the THR and RHR can be determined by reading the empty and full flags in
the Line Status Register (LSR). When the transmitter and receiver are ready to transfer data to and from the
FIFOs, interrupts are raised to signal this condition. Additionally, the user can use the Receive FIFO Data
Counter (RFDC) and Transmit FIFO Data Counter (TFDC) registers to determine the number of items in
each FIFO.
