Example 7:
To make LED_1 and LED_0 blink in turn of 1 Hz for 3 times.
// Assume both LED_0 and LED_1 LEDs are initially OFF. //
// The Initial LED_1 Blinking State is ON; The Initial LED_0 Blinking States is OFF //
// The buzzer will turn on during the T1 duration//
1 Hz = 1000 ms Time Interval = 500 ms ON + 500 ms OFF
