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 *2 data transfer stop condition, thus the transfer comes to close. *1 Defined by SDA fall down SCL during ‘H’ period. *2 Defined by SDA rise up SCL during ‘H’ period. (2) Transfer Data Format After transfer start condition, transfers slave address (92h : 1001 0010 ) to SDA terminal, control data, then, stop condition (See figure 1). Slave address is made up of 7bits, *3 8th bit shows the direction of transferring data, but this IC does not have READ mode, so that this bit fix to “L”. 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. *3 It is called R/W bit.
