STK1000/TWI interface
From AVRFreaks Wiki
Two Wire Interface (TWI) is used for generic serial communication between AVR32 processors and peripherals.
The TWI is not used on the STK1000 Motherboard. This interface is routed from the daughter board to the PCI style expansion connector and the general expansion headers.

Notes to developers
Note that no pull-up resistor is connected to the clock and data wire of the TWI interface on STK1000. If a pull-up resistor is required this must be mounted on the device connected to STK1000.
