Functional Description

Start Condition

A high-to-low transition of the SDA with the SCL high is needed in order to start read, write operation. (See start

condition and stop condition)

Stop Condition

A low-to-high transition of the SDA with the SCL high is a stop condition. The stand-by operation starts after a read

sequence by a stop condition. In the case of write operation, a stop condition terminates the write data inputs and place

the device in a internally-timed write cycle to the memories. After the internally-timed write cycle which is specified

as tWC, the device enters a standby mode. (See write cycle timing)
