7.3 Sequential read
Rev.3.0
When the E
current and random read operations following the start condition signal, it outputs the acknowledge signal.
When 8-bit data is output from the E
counter inside the E
8th data is output.
When the master device transmits the acknowledge signal, the next memory address data is output.
When the master device transmits the acknowledge signal, the memory address counter inside the
E
When the master device does not output an acknowledge signal and transmits the stop condition signal, the
read operation is finished.
Data can be read in the “Sequential Read” mode in succession. When the memory address counter reaches
the last word address, it rolls over to the first memory address.

PROM is incremented and data can be read in succession. This is called “Sequential Read”.
