Functional Description and Application Information
4.32.5.2.2
A COP timeout will generate a reset. See COP description for details.

The interrupts/reset vectors requested by the 9S12I32PIMV1 are listed in
addresses and priorities.
4.32.6.1
4.32.6.1.1
The 9S12I32PIMV1 generates a FLL Lock interrupt when the lock condition (LOCKST status bit) of the FLL has changed, either
from a locked state to an unlocked state or vice versa. Lock interrupts are locally disabled by setting the LOCKIE bit to zero. The
FLL Lock interrupt flag (LOCKIF) is set to1 when the lock condition has changed, and is cleared to 0 by writing a 1 to the LOCKIF
bit.
