8 / 20 page M24256-A 8/20 The output data comes from consecutive address- es, with the internal address counter automatically incremented after each byte output. After the last memory address, the address counter ‘rolls-over’ and the memory continues to output data from memory address 00h. Acknowledge in Read Mode In all read modes, the memory waits, after each byte read, for an acknowledgment during the 9th bit time. If the master does not pull the SDA line low during this time, the memory terminates the data transfer and switches to its stand-by state. Current Address Read The device has an internal address counter which is incremented each time a byte is read. For the Current Address Read mode, following a START condition, the master sends a Device Select Code with the RW bit set to ‘1’. The memory acknowl- edges this, and outputs the byte addressed by the internal address counter. The counter is then in- cremented. The master terminates the transfer with a STOP condition, as shown in Figure 8, with- out acknowledging the byte output. Sequential Read This mode can be initiated with either a Current Address Read or a Random Address Read. The master does acknowledge the data byte output in this case, and the memory continues to output the next byte in sequence. To terminate the stream of bytes, the master must not acknowledge the last byte output, and must generate a STOP condition. Figure 7.
