GENERAL PURPOSE I/O
The ADuC7032 features 9 General Purpose bi-directional I/O
pins (GPIO). In general, many of the GPIO pins have multiple
functions which 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 and their sink capability is 0.8mA
and they can source 0.1mA.
The 9 GPIO are grouped into three ports, Port0, Port1 and
Port2. Port0 is 5 bits wide. Port1 and Port2 are both 2 bits wide.
The GPIO assignment within each port is detailed in Table 48.
A typical GPIO structure is shown Figure 34.
External Interrupts are present on GP0, GP5, GP7 and GP8.
This interrupts are level triggered and are active high. These
interrupts are not latched, therefore the interrupts source must
be present until either IRQSTA or FIQSTA are interrogated.
The Interrupt source must be active for at least 1 CD divided
core clock to guarantee recognition.

All port pins are configured and controlled by 4 sets (1 set for
each port) of four port specific MMRs:
where x corresponds to the port number 0,1 or 2
During normal operation, user code can control the function
and state of the external GPIO pins via these general purpose
registers. All GPIO pins will retain their external (high or low)
during power-down (POWCON) mode.
