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.

Shadow FIFO Enable.
This is a shadow register for the FIFO enable bit (FCR[0]). This can be used to
remove the burden of having to store the previously written value to the FCR in
memory and having to mask this value so that only the FIFO enable bit gets updated.
This enables/disables the transmit (XMIT) and receive (RCVR) FIFO's. If this
bit is set to zero (disabled) after being enabled then both the XMIT and RCVR
controller portion of FIFO's will be reset.
