23 0x002C PCINT0 Pin change interrupt request 0

24 0x002E PCINT1 Pin change interrupt request 1

25 0x0030 PCINT2 Pin change interrupt request 2

26 0x0032 PCINT3 Pin change interrupt request 3

27 0x0034 SPI, STC SPI serial transfer complete

28 0x0036 ADC ADC conversion complete

29 0x0038 WDT Watchdog time-out interrupt

30 0x003A EE READY EEPROM ready

31 0x003C SPM READY Store program memory ready

Note:

1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at

reset, see Memory programming

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.

The table below 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.

Table 12-2. Reset and Interrupt Vectors placement

BOOTRST IVSEL Reset Address Interrupt Vectors Start Address

1 0 0x0000 0x0002

1 1 0x0000 Boot Reset Address + 0x0002

0 0 Boot Reset Address 0x0002

0 1 Boot Reset Address Boot Reset Address + 0x0002

Note: The Boot Reset Address is shown in Table Boot size configuration in Boot Loader Parameters.

For the BOOTRST Fuse “1” means unprogrammed while “0” means programmed.

The most typical and general program setup for the Reset and Interrupt Vector Addresses in this device

is:
