Software-programmable for one of 256 different serial clock frequencies

•

Software-selectable acknowledge bit

•

Interrupt-driven, byte-by-byte data transfer

•

Arbitration-lost interrupt with automatic mode switching from master to slave

•

Calling address identification interrupt

•

Start and stop signal generation/detection

•

Repeated START signal generation
