Table 33: EVENTS ON/OFF
EVENTS OFF/ON Globally Disables/re-enables events Statement
Purpose EVENTS OFF command when executed will disable any events currently enabled (running). EVENTS
ON Command re-enables any events previously disabled through the EVENTS OFF command.
EVENTS ON is not a global enable of all declared events. Events status is indicated through bit #30 of
the DSTATUS register or by system flag ‘F_EVENTSOFF’. EVENTS OFF/ON allows for easy disable
and re-activation of events in sections of the main program or subroutines that the programmer
doesn’t want interrupted by event code.
Syntax EVENTS OFF Disables execution of all events
EVENTS ON Restores execution of previously enabled events.
Remarks Events are globally disabled after a program reset is made or a fault occurs. Events are re-enabled by
executing the individual EVENT ON statement following either a Reset or a Fault Condition.
