As long as it's not code to specifically interact with the CW software
it's ok.
I don't have a special axe to grind against CW (I use to love it under
ol' MacOS, though the new eclipse based one does seem to suck hard...
but then I never got a "licence" to use it past the demo anyway), it's
just that I don't want to start building SW interfaces to a foreign
tool.
BTW. My point of view is that this whole business about MSR:DE is a HW
design bug. There should be -no- (absolutely 0) interaction between the
SW state and the HW debugger for normal operations unless the user of
the debugger explicitly wants to change some state.
Cheers,
Ben.
