1. Function description
    1. Trigger the alarm interrupt by setting the alarm time.
    2. Configure the IO output through the alarm flag bit

2. Use environment

    /* Software development environment: the name and version number of the software tool used in the current project */
    IDE tool: KEIL MDK-ARM 5.21.1.0
      
    /* Hardware environment: the development hardware platform corresponding to the project */
    Development board: N32G031C8L7-STB V1.0



3. Instructions for use

    System Configuration;
        1. RTC clock source: LSI
        2. Serial port configuration:
                    - Serial port is USART1 (TX: PA9 RX: PA10):
                    - Data bits: 8
                    - Stop bit: 1
                    - Parity: none
                    - Baud rate: 115200


    Instructions:
        After compiling under KEIL, burn it to the evaluation board, power on, and the serial port will print out the time set by the alarm clock.
