ATmega48/88/168
• 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.
This bit is not available in ATmega48.
Assembly Code Example
C Code Example
Move_interrupts:
void Move_interrupts(void)
{
uchar temp;
}
; Get MCUCR
in
mov r17, r16
; Enable change of Interrupt Vectors
ori r16, (1<<IVCE)
out MCUCR, r16
; Move interrupts to Boot Flash section
ldi r17, (1<<IVSEL)
out MCUCR, r17
ret
/* Get MCUCR*/
temp = MCUCR
/* Enable change of Interrupt Vectors */
MCUCR = temp|(1<<IVCE);
/* Move interrupts to Boot Flash section */
MCUCR = temp|(1<<IVSEL);
