C BUS serial interface specification
(1) Data Transfer Manual
This IC adopts control method(I
2
C-BUS) with serial data, and controlled by two terminals which called SCL(serial
clock) and SDA (serial data).At first, set up
*1
the 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 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 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, 8th bit
*3
shows the direction of transferring data, if it is ‘L’ takes write mode (As 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.
*3 It is called R/W bit.
