Fig.-12 SEQUENTIAL READ CYCLE TIMING
（ Current Read ）
○If an Acknowledge is detected, and no STOP condition is generated by the master (μ-COM),
the device will continue to transmit the data. ï¼»It can transmit all data (2kbit 256word)ï¼½
○If an Acknowledge is not detected, the device will terminate further data transmissions
and await a STOP condition befere returning to the standby mode.
○The Sequential Read operation can be performed with both Current Read and Random Read.
NOTE) If an Acknowledge is detected with "Low" level, not "High" level, command will become
Sequential Read. So the device transmits the next data, Read is not terminated. In the
case of terminating Read, input Acknowledge with "High" always, then input stop condition.
