ADuC7039
GENERAL-PURPOSE INPUT/OUTPUT
The ADuC7039 features six general-purpose bidirectional
input/output (GPIO) pins. In general, the GPIO pins have
multiple functions that can be configured by user code. By
default, the GPIO pins are configured in GPIO mode. All
GPIO pins have an internal pull-up resistor, a sink capability
of 0.8 mA and a source capability of 0.1 mA. A typical GPIO
structure is shown Figure 28.
The six GPIOs are grouped into one 6-bit wide port. The GPIO
assignment within this port is detailed in Table 49.
During normal operation, user code can control the function
and state of the external GPIO pins by these general-purpose
registers. All GPIO pins retain their external level (high or low)
during power-down (POWCON) mode.
