MicroBlaze - Is it possible to hold the MicroBlaze in Reset and still have the OPB operational?

Description

General Description:

Is it possible to hold the MicroBlaze in Reset and still have the OPB operational?

Solution

The signal Debug_Rst (used with the MDM and JTAG_UART debug cores) could be ORed with another system reset, and, by holding this signal active after configuration, MicroBlaze will under reset until the system signal is inactive.

After the system reset signal is released, the normal debugging reset will continue to work.
