An I2C device with a twist. ADDR here is set by connecting it to SCL/SDA/GND/VCC (4 bits with one pin), and, INT pin here is called ALERT. By [Pradeep717], CC BY-SA 4.0 How do you avoid address co ...

2- Working of I2C communication protocol I2C makes use of SDA and SCL, which are 2 bi-directional open-drain lines for data communication. Serial Data (SDA) – Data transfer takes place via this pin.

The best part of I2C is that it is a bus that is available just about anywhere, covering a vast ecosystem of devices that offer it as a hardware-defined interface, while being uncomplicated enough ...

The DB-I2C-S-APB-BRIDGE runs off the APB Master external clock input within the ASIC / ASSP, providing a synchronous design while offering I2C spike filtering of SDA and SCL.
