This is a common misunderstanding. The spec states that Addresses are 7 bits, plus a read-write bit. When you implement the controller, its simple to treat the r/w bit as an address bit, and you’ll find older device that do it this way.
Because of this, its always better to specify which form of address you’re discussing. On schematics at work, we usually make 7-bit/8bit address tables to eliminate the ambiguity.
