*HSE frequency check routine:
*Checking the frequency value of HSE by using of HSI.
* When HSE is 3 ~ 25M,the HSE clock is effective ,When CH32F20x_D8 and CH32F20x_D6 used.
* When HSE is 32M,the HSE clock is effective ,When CH32F20x_D8C and CH32F20x_D8W used.
* When HSE is 3 ~ 25M,the HSE clock is effective ,When CH32V20x_D6 used.
* When HSE is 32M,the HSE clock is effective ,When CH32V20x_D8 and CH32V20x_D8W used.
*HSE value -the frequency of HSE
*MCO(PA8) - outputs the HSE clock
