SC16C754B
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
The FIFO ready register is a read-only register that can be accessed when any of the four
UARTs is selected CSA to CSD = 0, MCR[2] (FIFO Rdy Enable) is a logic 1, and loopback
is disabled. The address is 111.

Programmer’s guide
The base set of registers that is used during high-speed data transfer have a
straightforward access method. The extended function registers require special access
bits to be decoded along with the address lines. The following guide will help with
programming these registers. Note that the descriptions below are for individual register
access. Some streamlining through interleaving can be obtained when programming all
the registers.
