ATmega8515(L)
• Bit 0 – IVCE: Interrupt Vector Change Enable
The IVCE bit must be written to logic one to enable change of the IVSEL bit. IVCE is
cleared by hardware four cycles after it is written or when IVSEL is written. Setting the
IVCE bit will disable interrupts, as explained in the IVSEL description above. See Code
Example below.
Assembly Code Example
C Code Example
Move_interrupts:
void Move_interrupts(void)
{
}
; Enable change of interrupt vectors
ldi r16, (1<<IVCE)
out GICR, r16
; Move interrupts to boot flash section
ldi r16, (1<<IVSEL)
out GICR, r16
ret
/* Enable change of interrupt vectors */
GICR = (1<<IVCE);
/* Move interrupts to boot flash section */
GICR = (1<<IVSEL);
