title: Analog Devices I3C Controller

description:
  FPGA-based I3C controller designed to interface with I3C and I2C peripherals,
  implementing a subset of the I3C-basic specification. The IP core is tested
  on arm, microblaze, and arm64 architectures.

          The secondary clock, drives the internal logic asynchronously to the
          register map. The presence of this entry states that the IP Core was
          synthesized with a second clock input, and the absence of this entry
          indicates a topology where a single clock input drives all the
          internal logic.
