Hardware traps are exceptions or error conditions
that arise during run-time. They cause immediate
non-maskable system reaction similar to a stan-
dard interrupt service (branching to a dedicated
vector table location).
The occurrence of a hardware trap is
additionally signified by an individual bit in the
trap flag register (TFR). Except when another

higher prioritized trap service is in progress, a
hardware trap will interrupt any other program
execution.
Hardware trap services cannot not be interrupted
by standard interrupt or by PEC interrupts.
