7.4. Interrupt-driven debug communications

The examples given in Polled debug communications 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 in Example 7.1 and Example 7.2 can then be moved into an interrupt handler.

See Interrupt handlers for information on writing interrupt handlers.
