15.2.3.4.9 Read Control Register (RCREG). Read the selected control register and return
the 32-bit result. Accesses to the processor/memory control registers are always 32 bits in
size, regardless of the implemented register width. The second and third words of the
command effectively form a 32-bit address the Debug module uses to generate a special
bus cycle to access the specified control register. The 12-bit Rc field is the same as that
used by the MOVEC instruction.
