The BIOS has a watchdog timer that heartbeats with a driver in the OS. The watchdog timer can be a real source of pain and can also make a PIC system incredibly robust and reliable. In the worst case, the watchdog timer has to search (N/B) queues for expirations, but I assume the watchdog timer is not required to kill idle sockets in any particular order! The watchdog timer decrements the register value once for every tick of the 1-kHz clock supplied from the RTC analog section (see Figure 23-1). The watchdog timer is initially disabled and set to count 4,294,967,295 milliseconds before generating a watchdog reset The watchdog timer does not run when the chip is in its powered-down state Therefore, there is no master/shadow register pairing for the watchdog timer , and it must be reprogrammed after cycling power or resetting the block. In the bottom-up view, the job of the operating system is to provide for an orderly and controlled allocation of the processors, memories, and I/O devices among the various programs wanting them.
