💡 Hint

Common Mistakes

Using the disable constant instead of enable.

Confusing reset with enable.

The WDT_CTRL_ENABLE constant enables the watchdog timer to start counting down.

Fix the error in the code to correctly reload the watchdog timer counter.

Embedded C

WDT->RELOAD = [1];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Setting the reload register to zero, which does not reset the timer.

Using an undefined constant.

The watchdog reload register must be set to WDT_RELOAD_VALUE to reset the timer counter properly.

hard

Fill both blanks to configure the watchdog timeout and enable it.

Embedded C
