Chapter 3 MicroSim: Loop Flow Visualizer

This MicroSim lets you visually trace the behavior of a loop written in PIC24 assembly using instructions like DEC, CP, and BNE.

You’ll see:

• Each instruction executed step-by-step
• Branches (BNE) visually jumping back to labeled code
• Final program continuation indicated with ; ... more code
• Live W0 value and total loop iterations

Code Simulated:

MOV #5, W0      ; Load 5 into W0
LOOP:
DEC W0          ; Decrement W0
CP W0, #0       ; Compare to 0
BNE LOOP        ; If W0 != 0, loop back
; ... more code
