11.4.3 The Disassembled Code Window
A program may be debugged at the assembly level by opening the Disassembled Code window (aka, the
Assembly window). Single stepping and breakpoints are supported in this window. When the “Disassem-
bled Code” window is open, single stepping occurs instruction by instruction rather than statement by
statement. The figure below shows the “Disassembled Code” window for the example code, asm1.c.
Figure 11.2 Disassembled Code Window
The Disassembled Code window shows the memory address on the far left, followed by the opcode bytes,
followed by the mnemonics for the instruction. The last column shows the number of cycles for the
instruction, assuming no wait states. The total cycle time for a block of instructions will be shown at the
bottom of the window when the block is selected. The total assumes one execution per instruction, so the
user must take looping and branching into consideration when evaluating execution times.
