GPxDAT is a Port x configuration and data register. It configures
the direction of the GPIO pins of Port x, sets the output value
for the pins configured as output, and receives and stores the
input value of the pins configured as input.

SERIAL PORT MUX
The serial port mux multiplexes the serial port peripherals (two
I2Cs, an SPI, and two UARTs) and the programmable logic array
(PLA) to a set of 10 GPIO pins. Each pin must be configured to
its specific I/O function as described in Table 76.

1 Available only on the 80-lead ADuC7129.
Table 76 details the mode for each of the SPMUX GPIO pins.
This configuration has to be performed via the GP0CON,
GP1CON and GP2CON MMRs. By default these pins are
configured as GPIOs.
UART SERIAL INTERFACE
The ADuC7128/ADuC7129 contain two identical UART
blocks. Although only UART0 is described here, UART1
functions in exactly the same way.
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 baud rate
generation and has a network-addressable mode. The UART
function is made available on 10 pins of the ADuC7128/
ADuC7129 (see Table 77).
