Device, system and method to support communication of test, debug or trace information with an external input/output interface

A system comprising:

• integrated circuitry comprising:
• a functional interface compatible with a Universal Serial Bus (USB)-based protocol, wherein the functional interface is to receive information associated with a test, debug, or trace (TDT) operation from an external system;
• a network to transfer the information associated with the TDT operation to a component, wherein the component is to perform the TDT operation as least partially based on the information associated with the TDT operation;
• first interface logic coupled between the network and the functional interface, wherein the information associated with the TDT operation is exchanged from the functional interface to the network via the first interface logic;
• and
• second interface logic coupled to the first interface logic and to a memory or I/O space, wherein data associated with the TDT operation is to be accessed from the memory or I/O space, via the second interface logic, based on memory mapped input/output (MMIO) information.
