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.

- description:
|
|
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.
