Non-Qualified Symbols

Non-Qualified Symbols are using only the name of the source code identifier. These symbols are searched in several symbol tables as described below:

  1. Symbol table created for user- or signal functions. If such Debug Functions are used, then the symbols defined in here have priority.
  2. CPU Register Symbols of the CPU: R0 – R15, RL0 – RH7, DPP0 – DPP3.
  3. Local variables in the current function. The current function is determined by the value of the program counter.
  4. Static variables in the current module. The current module is determined by the value of the program counter. These symbols represent variables that are declared in the scope of a module and outside of a function.
  5. Global or public symbols of the application. Peripheral register symbols defined by µVision are also considered to be public symbols.
  6. Symbols created with the DEFINE command. These symbols are used for debugging and are not a part of the target program.
  7. System variables that monitor and change debugger characteristics. These variables are not part of the application. Refer to System Variables for details.
  8. CPU Driver Symbols (VTREGs) defined by the CPU driver. Refer to Virtual Registers (VTREGs) for details.

This search order is changed when a Literal Symbol is preceded with a back quote (‘), then CPU Driver Symbols (VTREGs) is searched instead of CPU Register Symbols.
