UIF:更新中断标记 (Update interrupt flag) 当产生更新事件时该位由硬件置’1’。它由软件清’0’。 若TIMx_CR1寄存器的UDIS=0、URS=0,当TIMx_EGR寄存器的UG=1时产生更新事件(软件对计数器CNT重新初始化); 若TIMx_CR1寄存器的UDIS=0、URS=0,当计数器CNT被触发事件重初始化时产生更新事件。
上表10.1.1 中,Reset(复位)、NMI(Non Maskable Interrupt,不可屏蔽中断)、HardFault(硬件异常)的优先级是固定的,且优先级是负数,也就是最高的(优先级数字越小,优先级越高)。剩下的异常或中断,都是可以通过修改NVIC的寄存器调整优先级(但不能设置为负数)。NVIC作为在内核里的外设,也是通过存储器映射的方式访问...
