Reminders:
1. The LED State operation will be performed after the LED Blinking operation is completed.
2. The LED will not change if the corresponding LED Mask is not enabled.
3. The LED will not blink if the corresponding LED Blinking Mask is not enabled. Also, the
number of repetitions must be greater than zero.
4. T1 and T2 duration parameters are used to control the duty cycle of LED blinking and Buzzer
Turn-On duration. For example, if T1=1 and T2=1, the duty cycle = 50%.
Note: Duty Cycle = T1/(T1 + T2).
5. To control the buzzer only, just set the P2 "LED State Control" to zero.
6. To make the buzzer operate, the "number of repetitions" must greater than zero.
7. To control the LED only, just set the parameter "Link to Buzzer" to zero.
