7.6. Setting and Running to Breakpoints
The Silicon Laboratories microcontroller devices support up to four hardware breakpoints. A breakpoint is
associated with a specific line of code. When the processor reaches a hardware breakpoint, the code execution
stops, and the IDE refreshes all debug and watch windows. The on-chip debug hardware allows for breakpoints to
be placed on any line of executable code, including code in Interrupt Service Routines. This section provides steps
to set a breakpoint on the line of source code that increments the Num_LED_Flashes variable.
1. If the device is running, stop execution using the “Stop” button or use the Debug → Stop menu option.
2. Scroll to the Timer3_ISR function (line 684) and right-click on the variable “Num_LED_Flashes”. In the context
3. Click the “Go” button or select the Debug → Go menu option.
4. After a short time, the IDE will show that the device is halted. A blue line will be placed in the editor window to
