Fig.16 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.
[
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.
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.

Using this command, writing is inhibited in lower half area. (00h to 7Fh address) If Write Protect Command is executed,
cannot cancel the protection permanently. (Onetime Rom)
This Command is cancelled, if Write Protect Command is already executed.
During this command, please be left WP unconnected or connect WP to GND.
This command need the period of t
WR
after stop condition just like Byte or Page Write command. During the t
WR
, next
command is ignored.
