⚫ I2C
▪ Two-wire I2C serial interface consisting of data line (SDA) and clock line (SCL)
▪ Supports one I2C interface, supports two standard modes with a maximum rate of 100Kbps and
a high-speed mode of 400Kbps, and supports clock stretching.
▪ Support I2C master or slave device
▪ Support 7-bit or 10-bit address addressing and support mixed transmission
▪ Receive and send buffers with 16 words depth
▪ Support DMA for data transmission and reception
▪ Support bus arbitration mechanism to realize communication capability of multi-master devices
▪ Wake-up from device address match for low power consumption
▪ Software configurable parameters: SDA hold time, slave address, etc.
