Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Writes will have no effect when FIFO_ACCESS == No, always readable.  This register
is use to enable a FIFO access mode for testing, so that the receive FIFO can be
written by the master and the transmit FIFO can be read by the master when FIFO's
are implemented and enabled. When FIFO's are not implemented or not enabled it
allows the RBR to be written by the master and the THR to be read by the master.
0 = FIFO access mode disabled
1 = FIFO access mode enabled
Note, that when the FIFO access mode is enabled/disabled, the control portion of
the receive FIFO and transmit FIFO is reset and the FIFO's are treated as empty.
