Sequential Read:

Sequential reads are initiated by either a current address read or a random read. If the EEPROM receives

acknowledgment “0” after 8-bit read data, the read address is incremented and the next 8-bit read data are

coming out. This operation can be continued as long as the EEPROM receives acknowledgment “0”. The

address will roll over and returns address zero if it reaches the last address of the last page. The sequential

read can be continued after roll over. The sequential read is terminated if the EEPROM receives

acknowledgment “1” (no acknowledgment) and a following stop condition.
