Watch Global Window
The Watch Global window displays and supports the modification of global variables
within the user’s C language-based source program. Each variable is located within the
Code, XDATA, IRAM, SFR dump spaces. If users could easily determine a variable’s
location, they could edit the variable directly. However, finding a global variable across
these many memory dump spaces is often perceived to be a tedious process.
The Watch Global window alleviates this problem by employing a map/symbol file; see
Figure 60.
