This involvessending a get started situation followed by the system addressword. The read/write little bit is consultant of the operationdesired. Provided that the internal write cycle has finished willthe EEPROM answer having a zero making it possible for the browse orwrite sequence to continue.Read through OperationsRead operations are initiated the exact same way as compose opera-tions with all the exception which the read/write select little bit in thedevice deal with term is set to one.

You can find two readoperations: byte go through and sequential read.BYTE Examine: A byte go through is initiated with a start conditionfollowed by a 7-bit data word address and also a higher go through little bit.The AT24C01 will respond by having an admit and thenserially output 8 details bits.

The microcontroller does notrespond by using a zero but does create a subsequent stopcondition.SEQUENTIAL Examine: Sequential reads are initiated thesame being a byte study. Just after the microcontroller receives an8-bit information word, it responds using an acknowledge.

As longas the EEPROM receives an accept, it will continueto increment the info term address and serially clock outsequential knowledge terms. When the memory deal with restrict isreached, the info phrase deal with will “roll over” and thesequential read through will go on.

The sequential browse opera-tion is terminated if the microcontroller does notrespond with the enter zero but does produce a followingstop ailment.
