Fig. 13 Current read cycle

1) With this IC, an internal address counter circuit increments the address one address at a time, and stores in

memory the last word address (n address) for which the Write or read command was executed.

2) This command reads only the data of the word address (n +1 address) following the last word address to be writ-

ten after the previous command has been executed.

3) If the ACK signal LOW following D0 is detected and no stop condition is sent from the master (microcomputer)

side, reading can be continued sequentially to the data of the next word address.

[The entire 1 kilobit (128 words) can be read.]

(Refer to "Fig. 15 Sequential read cycle.")

4) To terminate this command, HIGH is input for the ACK signal following D0, and the SDA signal rises at the HIGH

state of the SCL signal (stop condition), terminating the command.
