ATmega32(L)
2503C–AVR–10/02
The following code example shows one assembly and one C function for turning off the
WDT. The example assumes that interrupts are controlled (for example by disabling
interrupts globally) so that no interrupts will occur during execution of these functions.
Assembly Code Example
WDT_off:
; Write logical one to WDTOE and WDE
ldi
r16, (1<<WDTOE)|(1<<WDE)
out
WDTCR, r16
; Turn off WDT
ldi
r16, (0<<WDE)
out
WDTCR, r16
ret
C Code Example
void
WDT_off(void)
{
/* Write logical one to WDTOE and WDE */
WDTCR = (1<<WDTOE) | (1<<WDE);
/* Turn off WDT */
WDTCR = 0x00;
}
