The next 3 bits of the control byte are the device select bits A2, A1, A0. Your device uses I 2 Cor datashewt called 2-wire serial communication.

Can somebody explain to me further the interest of having those pins? I found out that it have 3 pins A0,A1,A2 which as specified in the datasheet are chip address input.

The one below is set to have address These bits are in effect the 3 least significant bits of the slave address. What are the address input pins used for in ds? They are used by the master device to select which of eight devices are to be accessed.
The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations. Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line.

In this communication protocol the master selects a slave by sending its address to the bus, and the specific slave identifies itself by this address. Andy aka k 10 Bence Kaulics 5, 10 23 Sign up using Email and Password.
Here is a picture of I 2 C ‘s message frame. As you can see there is a Slave Address field which is 7 bit long.
A xs1621 addition to Andy aka ‘s answer. Email Required, but never shown. Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices. Null 4, 10 22 I just bought a ds temperature sensor and started reading its datasheet.
