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 wide, regardless of register width. The second and third words of the command
form a 32-bit address, which the debug module uses to generate a special bus cycle to access the specified
control register. The 12-bit Rc field is the same the processor’s MOVEC instruction uses.
