I3C PHY & Controller
DTI I3C Controller provides the logic consistent with NXP I3C specification to support the communication of low-speed integrated circuits through I3C bus.
The IP facilitates software controllable by application processor through industry-standard AMBA interface. The bus interface is flexible and easily integrated into APB, AHB or AXI system bus.
