Automotive CXPI Communication Application Circuit C (LED Ambient Light Drive Board / CXPI Responder Node)

CXPI, a next‑generation automotive communication protocol, delivers low cost and high responsiveness to support efficient control of various in‑vehicle functions.
This reference design demonstrates an example of a CXPI responder node, implemented as an LED ambient light driving board with an integrated CXPI interface.
The CXPI interface IC TB9033FTG is employed, and four PWM outputs selected from its 16-channel GPIO are utilized to provide flexible control of WRGB LEDs.
