Load a previously saved Watch window?

Click the right mouse button in the window to open a menu. Select Load Watch to load

a previously saved watch into the currently selected watch. Or, select Import to load

Watch values.

Change the order of watch items?

Simply drag-and-drop items where you want them in the watch list.

Watch a single bit from a register?

Set the variable format to binary. See Section 13.30 “Watch/Locals Dialog”.

Watch a 16-bit variable?

Set the variable size to 16 bit. See Section 13.30 “Watch/Locals Dialog”.

Watch C pointers and structure members?

See Section 6.3.7 “C Language Usage – Watch Window”.

12.15 CALL STACK WINDOW

For dsPIC digital signal controller (DSC) devices, a call stack window is available to

view calls and gotos in executing code.

It is recommended that code optimization be turned off when using the call stack.

12.16 SPECIAL FUNCTION REGISTERS WINDOW

The Special Function Registers window displays the contents of the Special Function

Registers (SFRs) for the selected processor.

The format provided by this window is more useful for viewing the SFRs than the

normal file register window, since each SFR name is included and several number

formats are presented. Whenever a break occurs, the contents of the Special Function

Registers are updated.

• SFRs Window Display

• SFRs Window Menu

• SFRs Window FAQ

Note: If the program stops on the declaration of the function, the display will not

show the calling function.

Note: If a data memory register is not physically implemented on a device, it may

not appear in the SFR list. Some tools, such as simulators, may allow you

to see registers that do not exist on the actual device, such as prescalers.

Note: If “Freeze Peripherals On Halt” is selected, the I/O port bits in the SFR or

the Watch windows will not update when single stepping. The pin will be

modified, but the read request to retrieve the new value is blocked by the

freeze and cannot be updated until the next step or run command.
