The ST10F163 provides an excellent mechanism
to identify and to process exceptions or error con-
ditions that arise during run-time, called‘Hardware
Traps’.
Hardware traps cause an immediate
non-maskable system reaction which is similar to
a standard interrupt service (branching to a dedi-
cated vector table location). The occurrence of a
hardware trap is additionally signified by an indi-
vidual 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 ser-
vices can normally not be interrupted by standard
or PEC interrupts.
Table 7 shows all of the possible exceptions or
error conditions that can arise during run time.
