Above-High Analog Trigger Condition
Figure 4-27 shows the above-high analog trigger condition, the
trigger signal asserts when the input analog signal is higher
than the High_Threshold voltage. The Low_Threshold setting
is not used in this trigger condition.

Inside-Region Analog Trigger Ccondition
Figure 4-28 shows the inside-region analog trigger condition,
the trigger signal asserts when the input analog signal level
falls in the range between the High_Threshold and the
Low_Threshold voltages.
