The sequence for changing the Watchdog Timer configuration differs slightly between the safety levels. Separate procedures are described for each level.
| Assembly Code Example |
WDT_off: ; reset WDT WDR ; Write logical one to WDCE and WDE in r16, WDTCR ori r16, (1<<WDCE)|(1<<WDE) out WDTCR, r16 ; Turn off WDT ldi r16, (0<<WDE) out WDTCR, r16 ret |
| C Code Example |
void WDT_off(void) { /* reset WDT */ _WDR(); /* Write logical one to WDCE and WDE */ WDTCR |= (1<<WDCE) | (1<<WDE); /* Turn off WDT */ WDTCR = 0x00; } |
