timers and watchdog 定时计数器和看门狗
This makes the LTC6991 useful for intervalometers, watchdog timers and periodic wake-up timers with minimal components and effort.
这使LTC 6991适用于定时曝光控制计、看门狗定时器和周期性唤醒定时器,而所需的组件和工作量极少。
Another interesting MCU with unique watchdog functionality is the STM32F100 family of micros from STMicroelectronics, which have two watchdog timers.
另一个有趣的MCU具有独特的看门狗功能是STM 32f100系列意法半导体万分之一,其中有两个看门狗定时器。
Each watchdog has a selectable prescaler (from 1 to 64 k) that can be used to clock the watchdog timers which can also trigger DMA requests and capture compare channels.
每个看门狗具有一个可选择的预分频器(从1到64 K),可用于时钟看门狗定时器也能触发dma请求和捕获比较通道。
