实时时钟的预分频模块中包括一个20位的RTC预分频器。 如果用户在RTC_CR寄存器中设置了相对应的允许位。那么每一个TR_CLK周期中实时时钟都会产生一个秒中断;RTC的第二个模块是一个32位的可编程计数器,这个计数器可以被初始化为当前的系统时间。这个系统时间会按照TR_CLK周期进行累加,并与存储在RTC_ALR寄存器的可...
// CLK_SYSCLKConfig通过CLK_Prescaler值的最高位来区分是配置HSI分频,还是CPU分频的。这个函数有两个功能。而CLK_HSIPrescalerConfig是直接配置HSI分频的,CPU分频配置成1 void CLK_SYSCLKConfig(CLK_Prescaler_TypeDef CLK_Prescaler) { /* check the parameters */ assert_param(IS_CLK_PRESCALER_OK(CLK_Prescale...
