Table 34: EVENTS ON/OFF
EVENTS OFF/ON Globally Disables/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 reset is made. Events are re-enable by executing the individual
EVENT ON statement.

Syntax FAULT FaultNumber Sets system fault.
Faultnumber - constant in range 128-240
