Background Debug Mode (BDM)
5.5.3.3.10 Read Control Register (
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 as that used by the MOVEC instruction.

The only operand is the 32-bit Rc control register select field.
Control register contents are returned as a longword,
most-significant word first. The implemented portion of registers
smaller than 32 bits is guaranteed correct; other bits are undefined.
