4.5.2.2 Above-High analog trigger condition
Figure 41 shows the above-high analog trigger condition, the trigger signal
is generated when the input analog signal is higher than the
High_Threshold voltage, and the Low_Threshold setting is not used in this
trigger condition.

4.5.2.3 Inside-Region analog trigger condition
Figure 42 shows the inside-region analog trigger condition, the trigger
signal is generated when the input analog signal level falls in the range
between the High_Threshold and the Low_Threshold voltages. Note the
High_Threshold setting should be always higher than the Low_Threshold
voltage setting.
