2. The LED will not be changed if the corresponding LED Mask is not enabled.
3. The LED will not be blinking if the corresponding LED Blinking Mask is not enabled. Also, the
number of repetition must be greater than zero.
4. T1 and T2 duration parameters are used for controlling the duty cycle of LED blinking and Buzzer
Turn-On duration. For example, if T1=1 and T2=1, the duty cycle = 50%. #Duty Cycle = T1 / (T1 +
T2).
