STM32F030F4P6/STM8L151C8T6的详细描述：

Inter-integrated circuit interfaces (I 2 C) The devices feature three I 2 C bus interfaces which can operate in multimaster and slavemode. Each I2C interface can support standard (up to 100 kHz), fast (up to 400 kHz) andfast mode + (up to 1 MHz) modes. All I 2 C interfaces support 7-bit and 10-bit addressing modes, multiple 7-bit slave addresses(2 addresses, 1 with configurable mask). They also include programmable analog anddigital noise filters.In addition, it provides hardware support for SMBUS 2.0 and PMBUS 1.1: ARP capability,Host notify protocol, hardware CRC (PEC) generation/verification, timeouts verifications andALERT protocol management. It also has a clock domain independent from the CPU clock,allowing the I2Cx (x=1,3) to wake up the MCU from Stop mode on address match.The I2C interfaces can be served by the DMA controller.Refer to Table 7 for the features available in I2C1, I2C2 and I2C3
