Bidirectional SCL

The clock line needs to be bi-directional when using a MULTI-MASTER protocol and when using the synchronization protocol.

When you are using only one Master then this is not required since the clock will always be generated by this device. If you run Multi-master then this changes. One master must be able to receive data from another master. At that time it must be able to receive clock information via the clock line also.
