R1EX24032Axx00A
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).
