7-bit Addressing Mode
Bit 7:1 = ADD7-ADD1 Interface address .
These bits define the I
face. They are not cleared when the interface is
disabled (PE=0).
Bit 0 = ADD0 Address direction bit.
This bit is don’t care, the interface acknowledges
either 0 or 1. It is not cleared when the interface is
disabled (PE=0).
Note: Address 01h is always ignored.
10-bit Addressing Mode
Bit 7:0 = ADD7-ADD0 Interface address .
These are the least significant bits of the I
address of the interface. They are not cleared
when the interface is disabled (PE=0).

Bit 5:3 = Reserved
Bit 2:1 = ADD9-ADD8 Interface address .
These are the most significant bits of the I
address of the interface (10-bit mode only). They
are not cleared when the interface is disabled
(PE=0).
