The event jump operation occurs even if the block pattern has not been output
for the number of repeats set in the sequence program. When an event jump
operation occurs, a positive TTL-level pulse 40 to 50 clocks wide is output from
the front panel event output connector 48 to 53 clocks before the block pattern
switches.

Note: If an event exists before the event out starts rising, the event jump will be made at
the next block. If the the event is coming after the event out starts rising, the event jump
will be performed at the block after the next block.
The number of clock varies depending on the pattern size of that block. This is because
the clock is generated from the ECL clock circuit by dynamically dividing into 9 or 10
cycles.
