The C167CS also provides an excellent mechanism to identify and to process
exceptions or error conditions that arise during run-time, so-called ‘Hardware Traps’.
Hardware traps cause immediate non-maskable system reaction which is similar to a
standard 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 actual program execution. In turn, hardware trap services
can normally not be interrupted by standard or PEC interrupts.
