HN58X2402SFPIAG/HN58X2404SFPIAG
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 t_WC, the device enters a standby mode. (See write cycle timing)
