    ZH32L072 Functional Module:
    ZH32L072 Clock:
        After the CPU starts, the default system clock frequency is HSI 8MHz. After the program runs, the system clock frequency and clock source can be reconfigured. can The selected high-frequency clocks include:
        *A 4/8/16/22.12/24 MHz configurable internal high-precision HSI clock.
        *A 32 kHz configurable internal LSI clock.
        *4~32 MHz HSE clock, and can enable CSS function to detect HSE. If CSS fails, the hardware will automatically convert the system clock to HSI, and the HSI frequency is configured by the software, while the CPU NMI interrupt is generated.
        *A 32.768KHz LSE clock.
        *PLL clock, PLL source can choose HSI and HSE. If HSE source is selected, when CSS is enabled and CSS fails, PLL and HSE are turned off, and the hardware selects the system clock source as HSI.
        The AHB clock can be divided based on the system clock, while the APB clock can be divided based on the AHB clock. The highest clock frequency for AHB and APB is 72MHz.
