 		 #172673 - Emulator trace
Responding to: ???'s previous message
I'm new to the tracer, so let me know if there's a better way to do this:

The instruction is:
max3140_configVar = 0; // int at 0x0501 in xdata

Save filename.txt

I'm not too sure how to evaluate the trace, but I can see in emulation that the variable is not cleared. The emulator can't manually write to the value either, which looks like I've misconfigured something.
