FPB BreakPoint(without Debugger)

Hello,
My App (cortex m4) needs to set up a breakpoint directly from code, in order to jump to an interrupt when an instruction from a certain address is fetched.
This without using a debugger.
I searched in the forum and tried the method.

1. DebugMon Enable
2. FP_COMP Setting
3. FP_CONT SET

But Never jump to DebugMon_Handler.
I wonder if any other settings are needed.

Best regards

I found the reason. The key of FP_CONT must also be set. (*(volatile unsigned int*)0xE0002000) |= 0x3;
