The following code example shows one assembly and one C function for turning off the
WDT. The example assumes that interrupts are controlled (e.g., by disabling interrupts
globally) so that no interrupts will occur during execution of these functions.
Assembly Code Example
C Code Example
WDT_off:
void WDT_off(void)
{
}
; Write logical one to WDCE and WDE
ldi
out
; Turn off WDT
ldi
out
ret
/* Write logical one to WDCE and WDE */
WDTCR = (1<<WDCE) | (1<<WDE);
/* Turn off WDT */
WDTCR = 0x00;
