JTAG/SWD and entering debug monitor

How does a JTAG/SWD debugger know when BKPT is executed? My guess is that BKPT triggers entry to debug monitor and entering debug monitor sets something in the debug port, but what, and how does a debugger...

Hi all Hope someone can help me a bit. I can get the SWD to work, or partial at least. JTAG not at all JTAG: If I select JTAG as the interface in KEIL, the CPU can be detected and the interface...
