External interrupt capability

This mode allows the Input capture capabilities to be used as external interrupt sources.

The interrupts are generated on the edge of the ARTICx signal.

The edge sensitivity of the external interrupts is programmable (CSx bit of ARTICCSR

After fetching the interrupt vector, the CFx flags can be read to identify the interrupt source.

During Halt mode, the external interrupts can be used to wake up the micro (if the CIEx bit is

set).
