Innosilicon I3C IP supports I3C master/slave functions, compliant with JESD403-1B and MIPI I3C. Users read and write the internal registers through the APB3.0 interface, and DMA is also supported for the internal data buffer write or read. I3C Master converts the parallel data, which are configured by the users, into SDL/SDA serial data. At the same time, I3C Slave converts the data of register reading and writing into SCL/SDA.
