01
Separate CC and PD controller blocks model the signal negotiation path before the switch matrix.
02
VBUS load switch is placed parallel to the CC/PD switch matrix to handle power routing.
03
Boundary in/out ports mark the external USB-C source and downstream sink.
Reuse for USB-C dock, hub, or dongle wiring diagrams where CC/PD switching and VBUS power paths must be documented.
