In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).
The detection of a RESET signal causes the processor to enter a system initialization period of six clock cycles, after which it sets the interrupt request disable flag in the status register and loads the program counter with the values stored at the processor initialization vector ($00FFFC – $00FFFD) before commencing execution.

Signal handling is vulnerable to race conditions. As signals are asynchronous, another signal (even of the same type) can be delivered to the process during execution of the signal handling routine. The sigprocmask(2) call can be used to block and unblock delivery of signals. Blocked signals are not delivered to the process until unblocked.
One pin receives the timer restart ("kick" [a]) signal from the computer; another pin outputs the timeout signal. A watchdog timer ( WDT , or simply a watchdog ), sometimes called a computer operating properly timer ( COP timer ), [ 1 ] is an electronic or software timer that is used to detect and recover from computer malfunctions.
In computing, the reset vector is the default location a central processing unit will go to find the first instruction it will execute after a reset. The reset vector is a pointer or address , where the CPU should always begin as soon as it is able to execute instructions.
