should be always higher then the Low_Threshold voltage set-
ting.
Figure 4-34: Inside-Region analog trigger condition
High-Hysteresis analog trigger condition
Figure 4-35 shows the high-hysteresis analog trigger condition,
the trigger signal is generated when the input analog signal
level is greater than the High_Threshold voltage, and the
Low_Threshold voltage determines the hysteresis duration.
Note the High_Threshold setting should be always higher then
the Low_Threshold voltage setting.
Figure 4-35: High-Hysteresis analog trigger condition
Low-Hysteresis analog trigger condition
Figure 4-36 shows the low-hysteresis analog trigger condition,
the trigger signal is generated when the input analog signal
level is less than the Low_Threshold voltage, and the
