C161U
Architectural Overview
With an interrupt response time within a range from just 140 ns to 280 ns (in case of
internal program execution), the C161U is capable of reacting very fast on non-
deterministic events.
Its fast external interrupt inputs are sampled every 28 ns and allow to recognize even
very short external signals.
C161U 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 an immediate non-maskable system reaction which is similiar 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 for another higher prioritized trap service being in progress, a hardware trap will
interrupt any current program execution. In turn, hardware trap services can normally not
be interrupted by standard or PEC interrupts.
Software interrupts are supported by means of the 'TRAP' instruction in combination with
an individual trap (interrupt) number.
