Cortex M3 ITM trace

Do I miss something or there is no way to implement interrupt driven debug trace on Cortex M3?

I know that the SWO interface is relatively fast, but still I would prefer to avoid any polling and blocking...

    I'm afraid there is no interrupt support for ITM stimulus registers.
    Instead of using ITM you might need to use a UART for interrupt driven text output.
    The debug monitor exception only linked to breakpoint and watchpoint events and does not get trigger by the ITM buffer status.
