(4) “Set 16M” button
Set MCLK(Master Clock) to 16MHz.
(5) “A/CHG” toggle
If checked, the interval of the frequency set by Min. and Max. can be periodically set
and tested according to the Step.
Example) In the above case, the frequency increases between 5 and 30 MHz in units of 0.
5 MHz, and the period increases by 0.5 x 1000 ms = 500 ms as the number next
to A / CHG.
