8.6 Interrupt-driven debug communications
The examples given above demonstrate polling the DCC. You can convert these to interrupt-driven examples by
connecting up COMMRX and COMMTX signals from the Embedded ICE logic to your interrupt controller.
The read and write code given above could then be moved into an interrupt handler.
See Interrupt handlers for information on writing interrupt handlers.
