独立看门狗IWDG——有独立时钟（内部低速时钟LSI---40KHz），所以不受系统硬件影响的系统故障探测器。主要用于监视硬件错误。 
窗口看门狗WWDG——时钟与系统相同。如果系统时钟不走了，这个狗也就失去作用了，主要用于监视软件错误。 
独立看门狗
看门狗定时时限=IWDG_SetReload()的值 / 看门狗时钟频率
看门狗时钟频率=LSI（内部低速时钟）的频率（40KHz）/ 分频数
独立看门狗(IWDG)由专用的40kHz的低速时钟为驱动。因此，即使主时钟发生故障它也仍然有效。
窗口看门狗由从APB1时钟分频后得到的时钟驱动，通过可配置的时间窗口来检测应用程序非正常的过迟或过早的行为。
IWDG_SetPrescaler() 分频，4~256
IWDG_SetReload() 计数值12位 0~0x0FFF
IWDG_ReloadCounter() 喂狗，必须在计数值减到1之前喂狗
IWDG_PR和IWDG_RLR寄存器具有写保护功能。要修改这两个寄存器的值，必须先向IWDG_KR寄存器中写入0x5555。
以不同的值写入这个寄存器将会打乱操作顺序，寄存器将重新被保护。重装载操作(即写入0xAAAA)也会启动写保护功能。
