When dealt with, is obliged togenerate an acknowledge just after the reception of eachbyte. The grasp product need to create an additional clockpulse which is affiliated with this Admit little bit.The unit that acknowledges, must pull down theSDA line in the course of the admit clock pulse in these types of absent which the SDA line is secure Lower in the course of the HIGHperiod of the admit similar clock pulse. Ofcourse, setup and maintain moments need to be taken intoaccount.

In the course of reads, a grasp need to signal an stop ofdata into the slave by not generating an Admit biton the last byte that's been clocked from the slave.In such a case, the slave (24XX64) will depart the information lineHIGH to allow the master to create the Halt con-dition.

Gadget Addressing A regulate byte is the initial byte been given next theSTART problem in the grasp product (Determine 3-2).The regulate byte consists of the four bit manage code; forthe 24XX64 this is certainly set as 1010 binary for go through and writeoperations.

The next 3 bits on the command byte arethe chip find bits (A2, A1, A0). The chip select bitsallow the usage of as much as 8 24XX64 gadgets on thesame bus and they are accustomed to decide on which unit isaccessed.

The chip choose bits from the regulate byte mustcorrespond towards the logic stages about the corresponding A2,A1, and A0 pins for that device to respond. These bitsare in impact the three Most significant bits in the wordaddress.
