(5) “Use Ext, Ref, Clock” toggle
If the button clicks, you can use an external reference clock.
(6) “Configure Trigger” button
Trigger # 1 (CC1), Trigger # 2 (CC2) of the following conditions, is set depending on the
selected trigger Delay, Width, Blank.
Delay : 0 ~ 4095, Width & Blank : 0 ~ 65535
Minimum frequency can be set f=1/T , so 1 / ((4095 + 65535 + 65535) * 20ns ) = 369.8Hz.
Reference) If the default Delay/Width/Blank is set to 0/0/0, the total is 100ns (20+80),
so it is output at 10Mhz. As shown in the figure below, whenever the setting
value increases by 1, the value corresponding to the corresponding option
setting increases by 20ns.

Increasing the Width increases the width of the pulse, and increasing the Blank increases
the interval.
