What is the resolution of Watchdog timer (WDT) in the WDT controller?

WDT includes an 18-bit up-counting WDT counter that supports 8 timeout intervals and its clock source can be set to 10khz or HCLK/2048. The timeout interval can be set to overflow from bit 3, 5… or bit 17. If the clock source of WDT is 10khz, the smallest timeout interval is 1.6ms (2^(3+1)/10k) and ...

What is the main function of Watchdog Timer (WDT) controller?

The purpose of Watchdog Timer is to perform a system reset when system runs into an unknown state. User needs to clear the WDT counter before the WDT controller resets a chip if the chip is operating normally. Moreover, user can also use the WDT interrupt event, and use the WDT wake-up function to w...
