Diagnostic interrupt control by CPU states
● Diagnostic interrupts are blocked by the FM 352 when the CPU is in STOP mode.
● If none of the queued errors were cleared while the CPU was in STOP, the FM 352
reports all these errors as "incoming" event at the next CPU transition to RUN.
● If all existing errors were cleared while the CPU was in STOP, FM 352 does not report its
error-free state with a diagnostic interrupt at the next CPU transition to RUN.
