1. Function description

	1. Trigger interrupt by setting wake up time
	2. Configure IO output by wake up flag bit

2. Use environment

	Software development environment: KEIL MDK-ARM V5.25
	Hardware environment:
		1. based on the evaluation board N32L40XML-STB V1.0 development
		2. MCUN32L406MBL7

3. Instructions for use

	System configuration:

		1. periodic wake up clock source: RTCCLK (1HZ)
		2. Wakeup IO output: PC13
		3. Serial port configuration:

							- Serial port: USART1 (TX: PA9 RX: PA10) :
							- Data bit: 8
							- Stop bit: 1
							- Parity check: None
							- Baud rate: 115200

	Instructions:
		1. After compilation, it is burned to the evaluation board. After power-on, the serial port will print "Stop2 Wakeup From RTC" every 5s
		2. When set "#define RTC_ALARM_TEST_TYPE RTC_ALARM_TEST_TYPE_OUTPUT", compile and burn to evaluation board,After power-on, the PC13 is turned over every 5S(4s high level, 1S low level).

4. Matters needing attention
	None
