看门狗,又叫 watchdog timer,是一个定时器电路, 一般有一个输入,叫喂狗(kicking the dog or service the dog),一个输出到MCU的RST端,MCU正常工作的时候,每隔一段时间输出一个信号到喂狗端,给 WDT 清零,如果超过规定的时间不喂狗,(一般在程序跑飞时),WDT 定时超过,就会给出一个复位信号到MCU,使MCU复位. ...

A watchdog timer interrupts after a certain time has expired. As mentioned earlier, the M16C/26 watchdog timer can be set up for various time periods by configuring the BCLK and watchdog prescaler. The equations to calculate the period based on the BCLK source are shown in Figure 2. These...

The examples/watchdog is actually setting up a task software watchdog timer. This timer is using the BSP tick timer (PIT0) to test whether the task watchdog has expired and not using the on-chip core watchdog module. The on-chip core watchdog is partially setup in...
After power-on-reset, the device starts in default mode with watchdog timer expired, or default mode. All the registers are in the default settings. In default mode, the device keeps charging the battery with default 12-hour fast charging safety timer. At the end of the 12-hour, the ...
7208 Error writing to NVRAM 7209 The service processor boot watchdog timer expired and forced the service processor to attempt a boot from the other firmware image in the service processor flash memory 720A Power-off reset occurred. FipsDump should be analyzed: Possible software problem 28 Power ...
To keep the device in host mode, the host has to reset the watchdog timer regularly by writing 1 to REG01 Bit [6] before the watchdog timer expires. Once the watchdog timer expires, the MP2624 returns to default mode. VREF LDO Output The VREF LDO supplies the internal bias circuits ...
It is particuly usefull with microcontrollers that are equiped with a Watchdog Timer that resets the microcontroller if the loop() function appears to be blocking. The profiling classes SoftTimerProfiler, SoftTimerProfilerMillis and SoftTimerProfilerMicros provides an easy way to identify "blocking"...
