Preliminary Technical Data
SERIAL PORT MUX
Rev. PrB | Page 52 of 80
The Serial Port Mux multiplexes the serial port peripherals (two

C, SPI, UART) and the Programmable Logic Array (PLA) to a
set of ten GPIO pins. Each pin must be configured to one of its
specific I/O function as described in Table 34.

Table 34 details the mode for each of the SPMUX GPIO pins.
This configuration has to be done via
the GP0CON, GP1CON
and GP2CON MMRs. By default these ten pins are configured
as GPIOs.
UART SERIAL INTERFACE
The UART peripheral is a full-duplex Universal Asynchronous
Receiver/Transmitter, fully compatible with the 16450 serial
port standard. The UART performs serial-to-parallel conversion
on data characters received from a peripheral device or a
MODEM, and parallel-to-serial conversion on data characters
received from the CPU. The UART includes a fractional divider
for baudrate generation and has a network addressable mode.
The UART function is made available on the following 10 pins
of the ADuC702x:
Pin
SPM0 (mode 1)
SPM1 (mode 1)
SPM2 (mode 1)
SPM3 (mode 1)

The serial communication adopts a asynchronous protocol that
supports various word length, stop bits and parity generation
options selectable in the configuration register.
Baud rate generation
There is two way of generating the UART baudrate.
-
Normal 450 UART baudrate generation:
The baudrate is a divided version of the core clock using the
value in COMDIV0 and COMDIV1 MMRs (16-bit value, DL).

Using the fractional divider:
The fractional divider combined with the normal baudrate
generator allows the generating of a wider range of more
accurate baudrates.
