External Interrupt Capability
This mode allows the Input capture capabilities to
be used as external interrupt sources. The inter-
rupts are generated on the edge of the ARTICx
signal.
The edge sensitivity of the external interrupts is
programmable (CSx bit of ARTICCSR register)
and they are independently enabled through CIEx
bits of the ARTICCSR register. After fetching the
interrupt vector, the CFx flags can be read to iden-
tify the interrupt source.
During HALT mode, the external interrupts can be
used to wake up the micro (if the CIEx bit is set). In
68/265
this case, the interrupt synchronization is done di-
rectly on the ARTICx pin edge
