I²C BUS Serial Interface Specification
(1) Data Transfer Manual
This LSI adopts control method (I²C-BUS) with serial data, and controlled by two terminals which called SCL
(serial clock) and SDA (serial data). At first, set up^*1the condition of starting data transfer, and after that, input 8 bit
data to SDA terminal with synchronized SCL terminal clock. The order of transferring is first, MSB (the Most Scale
of Bit), and save the order. The 9th bit takes ACK (Acknowledge) period, during SCL terminal takes ‘H’, this LSI
pull down the SDA terminal. After transferred the necessary data, two terminals lead to set up and of ^*2data transfer
stop condition, thus the transfer comes to close.
*1 Defined by SCL rise down SDA during ‘H’ period.
*2 Defined by SCL rise up SDA during ‘H’ period.
(2) Transfer Data Format
After transfer start condition, transfers slave address (1000 000*) to SDA terminal, control data, then, stop condition
(See figure 1).
Slave address is made up of 7bits, ^*38th bit shows the direction of transferring data, if it is ‘L’ takes write mode (As
this LSI side, this is input operation mode), and in case of ‘H’ reading mode (As this LSI side, this is output
operation mode).
Data works with all of bit, transfer the stop condition before stop 8bit transfer, and to stop transfer, it will be
canceled the transfer dates. At READ mode, this LSI outputs during ACK period, please must input 9 clocks.
*3 It is called R/W bit.
