Why does the MSP430 program fly?

The program of the MSP430 microcontroller is sometimes prone to fly, resulting in abnormal operation. The common causes are as follows:


The dog is not set to stop or be fed in time.

The interrupt function is not defined, but the corresponding interrupt is enabled. When the interrupt occurs, the interrupt function entry cannot be found.

The power supply voltage is unstable, or the input voltage of the I/O pin is too high, resulting in internal data interference.

Memory overflow. For example, functions such as sprintf are prone to this problem.
