I2C Serial Bus Timing

Note: Each session of data transfer is with a start condition, a 7-bits slave address plus a bit to instruct for read or write followed by an

acknowledge bit, a register address byte followed by an acknowledge bit, a data byte followed by an acknowledge bit and a stop condi-

tion. The device address, the register address and the data are all MSB first transferred. Each bit volume is prepared in during the SCL

is low, is latched-in by the rising edge of the SCL. The data byte is accepted and is put effective by the time that the last bit volume is

latched-in.
