ATmega325P/3250P

• 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

Move_interrupts:

;Get MCUCR

in

r16, MCUCR

mov

r17, r16

; Enable change of Interrupt Vectors

ori

r16, (1<<IVCE)

out

MCUCR, r16

; Move interrupts to Boot Flash section

ori

r17, (1<<IVSEL)

out

MCUCR, r17

ret

C Code Example

void

Move_interrupts(void)

{

/* Enable change of Interrupt Vectors */

MCUCR |= (1<<IVCE);

/* Move interrupts to Boot Flash section */

MCUCR |= (1<<IVSEL);

}
