Fig.14 CURRENT READ CYCLE TIMING
In case that the previous operation is Random or Current Read (which includes Sequential Read respectively), the
internal address counter is increased by one from the last accessed address (n).
Thus Current Read outputs the data of the next word address (n
+
1).
If the last command is Byte or Page Write, the internal address counter stays at the last address (n).
Thus Current Read outputs the data of the word address (n).
If an Acknowledge is detected, and no STOP condition is generated by the master (
μ
-COM), the device will continue to
transmit the data.
[
It can transmit all data (2kbit 256word)
]
If an Acknowledge is not detected, the device will terminate further data transmissions and await a STOP condition
before returning to the standby mode.
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.

Random Read operation allows the master to access any memory location indicated word address.
If an Acknowledge is detected, and no STOP condition is generated by the master (
μ
-COM), the device will continue to
transmit the data.

device transmits the next data, Read is not terminated. In the case of terminating Read, input Acknowledge with
“High” always, then input stop condition.
