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, from 194.5 to 214.5 clocks wide, is
output from the front–panel event output connector 180 to 200 clocks before the
block pattern switches. One half of one clock is the falling edge of the clock.

n: A value between 1 and the value determined by the iteration count
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.
