GENERAL-PURPOSE I/O
The ADuC706x features up to 16 general-purpose bidirectional
input/output (GPIO) pins. In general, many of the GPIO pins have
multiple functions that are configurable by user code. By default,
the GPIO pins are configured in GPIO mode. All GPIO pins have
an internal pull-up resistor with a drive capability of 1.6 mA.
All I/O pins are 3.3 V tolerant, meaning that the GPIOs support
an input voltage of 3.3 V.
When the ADuC706x enters power-saving mode, the GPIO
pins retain their state.
The GPIO pins are grouped into three port buses.
Table 110 lists all the GPIO pins and their alternative functions.
A GPIO pin alternative function can be selected by writing to
the correct bits of the GPxCON register.

GPxCON REGISTERS
GPxCON are the Port x (where x is 0, 1, or 2) control registers, which select the function of each pin of Port x as described in Table 112.
