The user-accessible MDM core Debug registers are listed and described in the following table. These registers are accessible using the Debug register access functionality. The values to write to the DBG_CTRL MDM register when accessing the MDM core debug registers are also listed in the table.
Additional MDM core commands are used to access MicroBlaze™ extended debug features, as defined in the MicroBlaze Processor Reference Guide (UG984).
All other MDM core commands are reserved for Xilinx internal use, to handle the JTAG debug protocol, including the JTAG UART and AXI Memory Access From Debug.
