Level and Edge operations
In the Level operation, a trigger is assumed to be generated if the trigger conditions are met when the [START]
key is pressed.
In the Edge operation, a trigger is not assumed to be generated even if the trigger conditions are met when
the [START] key is pressed.
A trigger is assumed to be generated when the trigger conditions, after not being met, are met again.
* A trigger is still assumed to be generated even if the trigger conditions are met once in the Edge operation
and then are no longer met.
