User Interface
The GPIO controls all the I/O pins on the AVR32 microcontroller. The pins are managed as 32-
bit ports that are configurable through a PB interface. Each port has a set of configuration regis-
ters. The overall memory map of the GPIO is shown below. The number of pins and hence the
number of ports are product specific.
Figure 17-6. Overall Mermory Map
In the GPIO Controller Function Multiplexingtable in the Package and Pinout chapter, each
GPIO line has a unique number. Note that the PA, PB, PC and PX ports do not directly corre-
spond to the GPIO ports. To find the corresponding port and pin the following formula can be
used:
GPIO port = floor((GPIO number) / 32), example: floor((36)/32) = 1
GPIO pin = GPIO number mod 32, example: 36 mod 32 = 4
The table below shows the configuration registers for one port. Addresses shown are relative to
the port address offset. The specific address of a configuration register is found by adding the
Port 0 Configuration Registers
Port 1 Configuration Registers
Port 2 Configuration Registers
