C163-L
The C163-L 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:
