20.5.1.1 I²C I/O Pins

Two pins are used for the bus operation. These are the SCLx pin, which is the clock, and the SDAx pin, which is the data. When the module is enabled, assuming no other module with higher priority has control, the module will assume control of the SDAx and SCLx pins. The user software need not be concerned with the state of the port I/O of the pins as the module overrides the port state and direction. At initialization, the pins are tri-stated (released).
