• 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 Inter?upt Vectors
ldi

/* Enable change of?Interrupt Vectors */
GICR = (1<<IVCE);
/* Move interrupts to Bo?t Flash section */
GICR = (1<<IVSEL);
