The following list describes the features of the watchdog timer:
  • Programmable 32‑bit timeout range
  • Timers counts down from a preset value to zero, then performs one of the following user‑configurable operations:
    • Generates a system reset †
    • Generates an interrupt, restarts the timer, and if the timer is not cleared before a second timeout occurs, generates a system reset
  • Dual programmable timeout period, used when the time to wait after the first start is different than that required for subsequent restarts †
  • Prevention of accidental restart of the watchdog counter †
  • Prevention of accidental disabling of the watchdog counter †
