It is possible to disable the TWI drivers in the device, and enable a four-wire digital interface for connecting to an external
TWI bus driver. This can be used for applications where the device operates from a different V

voltage than used by
the TWI bus.
It is also possible to enable the bridge mode. In this mode, the slave I/O pins are selected from an alternative port,
enabling independent and simultaneous master and slave operation.
