1. Function description

	1. Trigger the alarm interrupt by setting the alarm time.
	2. Configure I/O output through the alarm flag

2. Use environment

	Software development environment: KEIL MDK-ARM V5.25
	Hardware environment:
		1. based on the evaluation board N32L43XML-STB V1.0 development
		2. MCU: N32L436MBL7

3. Instructions for use

	System configuration:
		1. RTC clock source: LSE
		2. alarm 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:
		After compiling, it is burned to the evaluation board, powered on, and the serial port prints the output according to the time set by the alarm clock (1 minute by default).
		When set "#define RTC_ALARM_TEST_TYPE RTC_ALARM_TEST_TYPE_OUTPUT", at this time, the alarm clock output will be switched, and the flipped level will appear at port PC13.

4. Matters needing attention
	None
