5.2 Introduction to the Debugger Environment
There are four basic windows regarding the debugging operation in the debugger environment. They are Register
Window, Disassembly Window, Watch Window and Memory Window, as described below.
Register Window
This window shows the contents of the current register bank (R0~R7), the system registers (A, B, SP, DTPR and
the Program Counter) and the Program Status Word (PSW). The register with blue background means its content
is just changed due to the instruction just executed.
Disassembly Window
This window is the default window opened just when the debugger mode is entered. It shows the source-level
code followed by its corresponding assembly code.
Watch Window
This window automatically shows the local variables when
