the set code
Trigger occur when the Bus value is less than or equal to
the set code
For example, to measure an 8 bit data signal we need to observe when data value as 0X18
how the data changed before and after. We set the BUS0 to include CH00CH07 and use
channel CH00~CH07 to measure the signal. Trigger setting steps as below;
A. Press "Trigger menu" and menu appears.
B. Press "F1" till trigger mode display as "Bus"

insert data value "18" and set code as "0X18". Press "F3" again and red background
disappeared. Repeat operation of step D if setting error or need to be modified,
E. Press "F4" till type display as "="
