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