This IC adopts control method (I
clock) and SDA (serial data). At first, set up
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 IC pull down
the SDA terminal. After transferred the necessary data, two terminals lead to set up and of
condition, thus the transfer comes to close.
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,
this IC side, this is input operation mode), and in case of ‘H’ reading mode (As this IC 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.
*1 Defined by SCL rise down SDA during ‘H’ period.
*2 Defined by SCL rise up SDA during ‘H’ period.
*3 It is called R/W bit.
