Sequential Read

Sequential reads are initiated by either a current address read or a random address read. After the

microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM

receives an acknowledge, it will continue to increment the data word address and serially clock out

sequential data words. When

the memory address limit is reached, the data word address will “roll

over” and the sequential read will continue. The sequential read operation is terminated when the

microcontroller does not respond with a zero but does generate a following stop condition (refer to

Figure 12).
