World wide web site Deliver: The 2K EEPROM is able of an 8-byte webpage compose, coupled with the 4K, 8K and 16K goods are capable of 16-byte web page writes.

A webpage produce is initiated much like a byte produce, although the microcontroller wont deliver a stop affliction proper soon after the leading info term is clocked in. Alternatively, following the EEPROM acknowledges receipt along with the initial information phrase, the microcontroller can transmit as much as 7 (2K) or fifteen (4K, 8K, 16K) additional info phrases.

The EEPROM will react utilizing a zero immediately after every unique details expression gained. The microcontroller want to terminate the page compose sequence using a stop problem . The data phrase take care of reduce 3 (2K) or four (4K, 8K, 16K) bits are internally incre- mented adhering on the receipt of each information phrase.

The upper info expression deal with bits generally are certainly not incremented, retaining the memory website web page row place. When the phrase tackle, internally produced, reaches the positioning boundary, the next byte is positioned at first within the exact same website.

If much a lot more than 8 (2K) or sixteen (4K, 8K, 16K) information phrases are transmitted over the EEPROM, the information word tackle will “roll over” and previous information could possibly be overwritten.

Acknowledge POLLING: For the time the internally-timed make cycle has started off out in addition the EEPROM inputs are disabled, admit polling may well be initiated. This consists of send- ing a begin out circumstance accompanied from the product deal with phrase.
