Loader section of the Flash. The actual address of the start of the Boot Flash Section is deter-
mined by the BOOTSZ Fuses. Refer to Section “Memory programming” on page 359 for details.
To avoid unintentional changes of Interrupt Vector tables, a special write procedure must be fol-
lowed to change the IVSEL bit:
a.
Write the Interrupt Vector Change Enable (IVCE) bit to one.
b.
Within four cycles, write the desired value to IVSEL while writing a zero to IVCE.
Interrupts will automatically be disabled while this sequence is executed. Interrupts are disabled
in the cycle IVCE is set, and they remain disabled until after the instruction following the write to
IVSEL. If IVSEL is not written, interrupts remain disabled for four cycles. The I-bit in the Status
Register is unaffected by the automatic disabling.
Note:
If Interrupt Vectors are placed in the Boot Loader section and Boot Lock bit BLB02 is programmed,
interrupts are disabled while executing from the Application section. If Interrupt Vectors are placed
in the Application section and Boot Lock bit BLB12 is programed, interrupts are disabled while
executing from the Boot Loader section. Refer to the section “Memory programming” on page 359
for details on Boot Lock bits.
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)
{
unsigned char temp;
/* Get MCUCR */
temp = MCUCR;
/* Enable change of Interrupt Vectors */
MCUCR = temp | (1<<IVCE);
/* Move interrupts to Boot Flash section */
MCUCR = temp | (1<<IVSEL);
}
