11 / 14 page SMS2902/SMS2904/SMS2916 11 2028 5.1 8/2/00 Sequential READ Sequential READs can be initiated as either a current address READ or random access READ. The first word is transmitted as with the other byte read modes (current address byte READ or random address byte READ); however, the master now responds with an ACKnowledge, indicating that it requires additional data from the SMS29xx. The SMS29xx continues to output data for each ACKnowledge received. The master terminates the sequential READ operation by not responding with an ACKnowledge, and issues a STOP conditions. During a sequential read operation, the internal address counter is automatically incremented with each acknowl- edge signal. For read operations, all address bits are incremented, allowing the entire array to be read using a single read command. After a count of the last memory address, the address counter will ‘roll-over’ and the memory will continue to output data. See Figure 11 for the address, acknowledge and data transfer sequence.
