FIGURE 11-1: WATCH WINDOW WITH UPDATE
Click on a diamond in the “Update” column to alternately set/remove data capture or a
runtime watch. Right click in the “Update” column to see data capture and runtime
watch options, or right click on a diamond to pop up a menu with options for only data
capture or a runtime watch.
For PIC18, PIC24, dsPIC30F and dsPIC33F devices, data captures and runtime
watches use the same resource. For more information, see Chapter 7. “Debug for 8-
and 16-Bit Devices”
For PIC32MX devices, data captures and runtime watches use separate resources.
For more information, see Chapter 8. “Debug for 32-Bit Devices”.
11.3.10 Data Capture Properties Dialog
Select “Data Capture Properties” from the “Update” right click menu in the Watch win-
dow to see this dialog. The data capture properties dialog has the following options:
• Address or symbol to capture - The data address (in hex) for capture as specified
in the Watch window.
• When to capture entry - Specify if the capture happens on read or write from the X
bus.
Data capture can only be performed on register-sized variables.
• For PIC18 MCUs, only byte-sized variables can be captured.
• For dsPIC DSC/PIC24 devices, only 16-bit variables can be captured, such as
shorts and ints, but not floats and longs.

Note: The emulator simply displays data address (SFR) information that is sent
over the device ICE bus. Not all SFRs are on the device ICE bus, notably
SFRs in the core.
