Description of the function
The UNMASKEVT function performs global unmasking
of events.
The events that were stored during the masking period
are processed. The event processing mechanism is operational until
the next MASKEVT instruction.
NOTE: It is recommended to use this instruction only for short masking
sequence, in the same task cycle. In other cases,
%S38 should be used. Events are automatically unmasked by the system
on change of mode (stop -> run, ...). It is not recommended to execute
masking sequences when event timers are active, because they will
be reset to 0.The additional parameters EN and ENO can be configured.
