11.9.10 UART Register Locations
Table11-14 shows the registers associated with the UART and the physical addresses used to
access them. See the Section11.9, “Serial Port 1 – SDLC/UART” on page 11-78 for a description
of the programming and operation of the UART (serial port 1’s UART is identical to serial port 3’s
UART).
