FIFOSEL
FIFO select.
For backward compatibility with 16C550, 16C650 and
16C750 devices the FIFO depth of both UARTs is 16 when
FIFOSEL is low. The FIFO size of both UARTs is increased
to 128 when FIFOSEL is high.
The FIFO size of each UART may also be set to 128 by
setting the UARTs FCR[5] when LCR[7] is set, or by putting
the device into enhanced mode.
The unlatched state of this pin is readable by software.
