The fabric configuration interface (APB3) allows the user to dynamically update the attributes of the GTME5_QUAD primitive. The APB3 interface is a processor-friendly synchronous interface with an address bus (APB3PADDR) and separate data buses for reading (APB3PRDATA) and writing (APB3PWDATA) configuration data to the primitive. An enable signal (APB3PENABLE), a read/write signal (APB3PWRITE), and a ready/valid signal (APB3PREADY) are the control signals that implement read and write operations, indicate operation completion, and indicate the availability of data.
