In 7-bit addressing mode
Bits 7:1 = ADD[7:1] Interface address. These bits define the I
interface. 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).
In 10-bit addressing mode
Bits 7:0 = ADD[7:0] Interface address. These are the least significant bits of the I
bus address of the interface. They are not cleared when the interface is disabled
(PE=0).
These bits are set by software only when the interface is disabled (PE=0). To configure
the interface to I
