The ESB Mux provides a thin layer around the ESB, which provides separate interface ports for APB and HSP, and an internal mux to select between the two. The mux is controlled by a new control register, which is mapped into unused ESB address space. This register is always available through the APB interface, regardless of whether the mux is set to APB or HSP.
