Functional Description
Data Sheet

V1.0, 2003-11
The C161S 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.
Table 4 shows all of the possible exceptions or error conditions that can arise during run-
time:
