5.6 DEBUGGING FUNCTIONS

When you select the MPLAB REAL ICE in-circuit emulator from the Debugger menu,

debug items will be added to the following MPLAB IDE functions:

• Debugger Menu

• Right Mouse Button Menu

• Toolbars/Status Bar

5.6.1 Debugger Menu

Run F9

Execute program code until a breakpoint is encountered or until Halt is selected.

Execution starts at the current program counter (as displayed in the status bar). The

current program counter location is also represented as a pointer in the Program

Memory window. While the program is running, several other functions are disabled.

Animate

Animate causes the debugger to actually execute single steps while running, updating

the values of the registers as it runs.

Animate runs slower than the Run function, but allows you to view changing register

values in the Special Function Register window or in the Watch window.

To Halt Animate, use the menu option Debugger>Halt

, the toolbar Halt or <F5>.

Halt F5

Halt (stop) the execution of program code. When you click Halt, status information is

updated.

Step Into F7

Single step through program code.

For assembly code, this command executes one instruction (single or multiple cycle

instructions) and then halts. After execution of one instruction, all the windows are

updated.

For C code, this command executes one line of C code, which may mean the execution

of one or more assembly instruction, and then halts. After execution, all the windows

are updated.

Step Over F8

In C code, steps over the current line of code.

Note: Do not step into a SLEEP instruction.
