FAQ
Under the premise that the MCU is not damaged, when a new Config setting value is programmed, why is the MCU will always reset after powered on? Issue Date：2018-11-27
A reset after the MCU is powered on may be caused by the following conditions:
(1) The user turns on the BOD function in the Config0 setting. When the input voltage of the chip is lower than the voltage setting value of the BOD, the system resets the MCU.
(2) The user turns on the watchdog timer (WDT) function in the config0 setting. If the user does not do the dog feed (Clear / Reload), the watchdog timer will be automatically reset after the set time has elapsed.
