the data word. The microcontroller does not respond with a

zero but does generate a following stop condition (refer to

Figure 5).

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 con-

tinue. 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 6).
