Specification exception
Possible causes are as follows:
Branch to an odd-numbered address, caused by an overlaid register save
area
I was too hasty with my original response. ANY branch to an odd address
generates a specification exception. The exception is recognized before
exceptions caused by a failure to fetch the storage. Therefore, the
result is 0C6 even if the storage does not exist or is fetch protected.
Technically, it's not the branch itself abending but I'm not going to
dwell on that...
