Processor Utility Box (UBOX) Registers
The UBOX is the piece of processor logic that deals with the non mainstream flows in 
the system. This includes transactions like the register accesses, interrupt flows, lock 
flows, and events. In addition, the UBOX houses coordination for the performance 
architecture, and also houses scratchpad and semaphore registers.
