The C164 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 occurence 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.
The following table shows all of the possible exceptions or error conditions that can arise
during run-time:
