These bits are in effect the 3 least significant bits of the slave address. Here is a picture of I 2 C ‘s message frame. Post as a guest Name.

Here’s what the data sheet says: Sign up or log in Sign up using Google. What are the address input pins used for in ds?
Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line. Your device uses I 2 Cor often called 2-wire serial communication.

They are used by the master device to select which of eight devices are to be accessed. As you can see there is a Slave Address field which is 7 bit long. Email Required, but never shown.
The one below is set to have address Sign up using Email and Password. The next 3 bits of the control byte are the device select bits A2, A1, A0. 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.
Can somebody explain to me further the interest of having those pins? Home Questions Tags Users Unanswered. ChiPlusPlus 1 1 I found out that it have 3 pins A0,A1,A2 which as specified in ds11621 datasheet are chip address input.
Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices. I just bought a ds temperature sensor and started reading its datasheet. Null 4, 10 22 The control byte consists of a 4-bit control datashet for the DS, this is set as binary for read and write datashest.
