9.1i EDK - MicroBlaze v6 is showing erroneous values on the Trace_Exception_Kind signal

Description

When C_AREA_OPTIMIZED = 1, MicroBlaze version 6 will show an extra erroneous exception on the trace output signal Trace_Exception_Kind before a valid exception is taken. Only the Trace_Exception_Kind signal is in error, as MicroBlaze will not execute the erroneous exception.

Solution

Do not use this signal in hardware or software. If this signal must be used, then C_AREA_OPTIMIZED must be set to 0. The ESR register will contain the proper information. This problem is fixed in MicroBlaze v7.
