Transmit and receive data register. Writing to this register pushes a byte onto the transmit
FIFO. Reading from this register pulls a byte from the receive FIFO.
The baud rate period (N) of the clock rate as seen in the equation: rate = 24MHz / ( 2 * ( N +
(0.5*F) ) )
The baud rate fractional remainder (F) of the clock rate as derived from the equation: rate =
24MHz / ( 2 * ( N + (0.5*F) ) )
