VII - INTERRUPT SYSTEM (continued)
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 regis-

ter (TFR). Except when another higher prioritized
trap service is in progress, a hardware trap will
interrupt any actual program execution. In turn,
hardware trap services can normally not be inter-
rupted by standard or PEC interrupts.
