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 maximum address is reached, the data word address will roll-over and the Sequential Read will
continue from the beginning of the array. The Sequential Read operation is terminated when the microcontroller does not
respond with a zero but does generate a following stop condition (See Figure 9-3 ).
