有什么可以避免恒指下跌？

大家好，

我正在STM8L-discovery上编写STM8L152C6。想要提高救援能力，我要降低恒生指数。为此，我使用指令
//时钟源

CLK_LSICmd（ENABLE）;

CLK_SYSCLKSourceConfig（CLK_SYSCLKSource_LSI）;
while（（（CLK-> ICKCR）＆amp;＆amp; CLK_ICKCR_LSIRDY）== 0）;
CLK_SYSCLKSourceSwitchCmd（ENABLE）;
CLK_HSICmd（DISABLE）;
CLK_SYSCLKDivConfig（CLK_SYSCLKDiv_1）;
根据我在本网站上看到的主题，对某些人来说似乎有用。我正在完美地切换时钟源，CLK_ICKCR中的HSION位为0.但CLK_ICKCR中的HSIRDY是钢到1，CLK_REGCSR中的HSIPD是0.我暂时没有使用任何外设。

难道我做错了什么？有什么可以避免恒指下跌？

我希望有一个人可以帮助我。非常感谢你。

Hello everybody,

I'm programming a STM8L152C6 on the STM8L-discovery. Wanting to improve the consomption I tri to power down the HSI. For that I use the instruction
  // Clock source

   CLK_LSICmd(ENABLE);

   CLK_SYSCLKSourceConfig(CLK_SYSCLKSource_LSI);
   while(((CLK->ICKCR) && CLK_ICKCR_LSIRDY)==0);
   CLK_SYSCLKSourceSwitchCmd(ENABLE);
   CLK_HSICmd(DISABLE);
   CLK_SYSCLKDivConfig(CLK_SYSCLKDiv_1);
What seems to work for some people according to the topics I read on this site. I'm switching the clock source perfectly and the HSION bit in the CLK_ICKCR is 0. But the HSIRDY in the CLK_ICKCR is steel to 1 and the HSIPD in the CLK_REGCSR is to 0. I'm not using any peripheral for the moment.

Am I doing something wrong? What could avoid the HSI to turn down?

I hope someone can help me. Thank you very much.
