µVISION DEBUGGER: ACCESSING SPECIAL VARIABLE NAMES


Information in this article applies to:

  • µVision Version 2.20

QUESTION

I load my program into the debugger and try to watch the variables a, b, and state in my program. The watch window shows strange values that are not correct for my variables. What's going on?

ANSWER

By default, the debugger uses the name A to reference the accumulator (in the 51 and 251), B to access the B register (in the 51 and 251) and STATE to access the number of machine states that have occurred. To access the variables from your program named a, b, and state, use a back quote before the variable. For example:

ws 'a
ws 'b
ws 'state

This adds watchpoints for your variables.
