WebFeb 16, 2024 · I2C Communication Protocol. I2C stands for Inter-Integrated Circuit. It is a bus interface connection protocol incorporated into devices for serial communication. It was originally designed by Philips Semiconductor in 1982. Recently, it is a widely used protocol for short-distance communication. It is also known as Two Wired Interface (TWI).

WebOn Rockchip I2C the controller drops SDA low in the repeated start condition at half the SCL high time. If we want to meet timing requirements, that means we need to hold SCL high for (4.7us * 2) when we're sending a repeated start (.6us * 2 for Fast-mode).
