Acknowledge POLLING: When the internally-timed write cycle has started out and also the EEPROM inputs are disabled, admit polling may be initiated. This will involve sending a start ailment adopted through the gadget deal with word.

The read/write little bit is agent from the operation desired. Only if the internal write cycle has completed will the EEPROM respond that has a zero making it possible for the read or create sequence to continue.

Read through operations are initiated the exact same way as compose functions together with the exception that the read/write find little bit inside the machine handle term is about to at least one. You will find two read through functions: byte study and sequential browse.

BYTE Study: A byte go through is initiated using a commence condition followed by a 7-bit info term deal with plus a higher read little bit. The AT24C11 will reply with the admit and afterwards serially output eight details bits. The microcontroller won’t react which has a zero but does make a next quit issue.

SEQUENTIAL Study: Sequential reads are initiated precisely the same as being a byte examine. After the micro- controller gets an 8-bit details word, it responds having an acknowledge. Providing the EEPROM receives an acknowledge, it’s going to carry on to increment the data phrase address and serially clock out sequential data text.

When the memory address limit is reached, the information term handle will “roll over” along with the sequential read through will proceed. The sequential browse operation is terminated when the microcontroller isn’t going to answer having an enter zero but does make a adhering to cease situation .
