5. Device addressing

To perform data communications, the master device mounted on the system outputs the start condition signal

to the slave device. Next, the master device outputs a 7-bit device address and a 1-bit read/write instruction

code onto the SDA bus.

The higher 4 bits of the device address are called the “Device Code”, and are fixed to “1010”. The following 3

bits are “don’t care” bits.

When the comparison results match, the slave device outputs the acknowledge signal during the 9th clock

cycle.
