6.数据帧格式（DataFrameFormat）：I2C通信的数据帧通常包括一个起始位、7位或10位的设备地址、读/写位（R/Wbit）、数据位和校验位（如果启用）。7.时钟极性和相位（ClockPolarityandPhase）：I2C总线的时钟信号可以有不同的极性（高电平或低电平）和相位（数据采样的时机）。这些参数需要匹配通信设备的要求。8....
Data bits can be sent in a serial or parallel format. In parallel communication, data bits are sent over the cable at the same time. The parallel transmission of the character "C" in binary (01000011) is shown in the diagram below: Bits are delivered one by one across a single wire...

Data Frames After the address frame has been sent, data can begin being transmitted. The controller will simply continue generating clock pulses at a regular interval, and the data will be placed on SDA by either the controller or the peripheral, depending on whether the R/W bit indicated a...
