This command sets Standard Event Status Register bit 0 to “1” when all previous commands have
been executed and changes in output level have been completed. This command does not prevent
processing of subsequent commands, but bit 0 will not be set until all pending operations are com-
pleted. (1 = set = enable function, 0 = reset = disable function).
