These registers are accessed through the BDM port by new BDM commands,
RDMREG
contain a 5-bit field, DRc, that specifies the register, as shown in Table 5-6.
Note: Each debug register is accessed as a 32-bit register; shaded fields above are not used (don’t care).

All debug control registers are writable from the external development system or the CPU via the
WDEBUG instruction.
CSR is write-only from the programming model as debug control register 0x00 using the supervisor-mode
WDEBUG instruction. It can be read from and written through the BDM port using the
WDMREG
