6.2 Extended mode (128-byte FIFO)
The device is in the extended mode when any of these four registers contains any value
other than 0: FLWCNTH, FLWCNTL, TXINTLVL, RXINTLVL.
6.3 Internal registers
The SC16C850L provides a set of 25 internal registers for monitoring and controlling the
functions of the UART. These registers are shown in
Table 5
