Notes:
1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at
reset, see “Memory programming” on page 359.
2. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start of the Boot
Flash Section. The address of each Interrupt Vector will then be the address in this table
added to the start address of the Boot Flash Section.
Table 10-2 shows reset and Interrupt Vectors placement for the various combinations of
BOOTRST and IVSEL settings. If the program never enables an interrupt source, the Interrupt
Vectors are not used, and regular program code can be placed at these locations. This is also
the case if the Reset Vector is in the Application section while the Interrupt Vectors are in the
Boot section or vice versa.
Note:
1. The Boot Reset Address is shown in Table 29-8 on page 357. For the BOOTRST Fuse “1”
means unprogrammed while “0” means programmed.
10.1.1
Moving interrupts between application and boot space
The General Interrupt Control Register controls the placement of the Interrupt Vector table.
10.1.2
MCUCR – MCU Control Register
Bit 1 – IVSEL: Interrupt Vector Select
When the IVSEL bit is cleared (zero), the Interrupt Vectors are placed at the start of the Flash
memory. When this bit is set (one), the Interrupt Vectors are moved to the beginning of the Boot
