Below-Low analog trigger condition
Figure 4-32 shows the below-low analog trigger condition, the
trigger signal is generated when the input analog signal is less
than the Low_Threshold voltage, and the High_Threshold set-
ting is not used in this trigger condi-tion.

Above-High analog trigger condition
Figure 4-33 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.

Inside-Region analog trigger condition
Figure 4-34 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
