Its called "Power Up Reset", Or its called "Watch Dog Reset", if that is what you really mean. But, what is it you want to know ?? What processor are you using ? What peripherals are you concerned about ?? What are you talking about ??????

The watchdog timer should never overflow. If it does, something has gone horribly wrong. And it resets the processor, so whatever you flagged is likely gone. Might depend on the processor...RTFM Fix the code to detect the condition you're looking for. You can turn the led at boot and turn it off manually with a switch. If it's on after you reset it, there's been a reboot. Still, not a substitute for fixing the code.

Like most microcontrollers, it has a register holding the cause of reset. Note that you need to clear the various flags yourself after reading them - for obvious reasons, they are not cleared automatically at reset.

Start reading the datasheet of the MSP430. It should all be in there! Meindert
