The SAB 80C166W/83C166W 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-
