Capturing unused interrupts

The debugging system based on MON8 allows only one breakpoint placed in the flash memory. However, executing an SWI instruction while running is functionally equivalent to hitting a breakpoint, except that execution stops at the instruction following the SWI. The user can use this feature to actively capture unused interrupts. There are two options for capturing such interrupts:

• If the property named ' Unhandled interrupts' located in Build Options tab is set to Own handler for every, there is an interrupt routine generated for each unhandled interrupt generated into the Cpu.c module. The SWI instruction can be placed in the generated routine of the interrupt that need to be caught.
• You can also use the InterruptVector component. In the properties of the component, select which interrupt will be monitored and set the name of the ISR function, for example, Trap. One function can be used to capture more interrupts if property Allow duplicate ISR names is set to yes. The Trap function will contain only the SWI instruction:

  __interrupt void Trap(void)
   {
       asm(SWI);
   }
