I
2C BUS register
1) The explanation of I
2C Bus
I2C Bus (Inter IC Bus) is the bus system which the PHILIPS company developed.
It does controls such as the start, the stop by two control signals of SDA (Serial Data) and SCL (Serial Clock).
The output of each signal is open drain and forms out of wired OR.
S: Start condition
P: Stop condition
ACK: Acknowledge
Data is transmitted in the MSB first.
1 unit is composed of 8 bits and ACK is put back from the slave to confirm.
Slave IC reads data with rising edge of SCL.
Master IC changes data by falling edge in SCL.
