''void WDT_DISABLE()''

===== Commands =====

^ Command ^ Arguments ^ Return Value ^ Operation ^
| ''WDT_DISABLE()'' | None | ''void'' | Stops the Watchdog. |


===== Example =====

This example uses MPINO-16A8R8T digital input D22. When D22 becomes HIGH, it disables the watchdog once and does not enable it again.

<code cpp>
bool watchdogActive = true;

void setup() {
  WDT_ENABLE(WDT_2S);  // Start the two-second watchdog.
}

void loop() {
  if (watchdogActive && digitalRead(22) == HIGH) {
    WDT_DISABLE();  // Disable the watchdog when D22 becomes HIGH.
    watchdogActive = false;
  }
  if (watchdogActive) WDT();  // Feed the watchdog only while it is active.
  delay(100);
}
</code>

===== Precautions =====

  * Use time constants supported by the MCU.
  * Do not set a timeout shorter than the longest normal processing time.
  * Do not hide program faults by placing ''WDT()'' where it always executes unconditionally.
