10. Interrupts
This section describes the specifics of the interrupt handling as performed in ATtiny43U. For a
general explanation of the AVR interrupt handling, see “Reset and Interrupt Handling” on page
13.
10.1
Interrupt Vectors
If the program never enables an interrupt source, the Interrupt Vectors are not used, and regular
program code can be placed at these locations. The most typical and general program setup for
the Reset and Interrupt Vector Addresses in ATtiny43U is:
Address
Labels Code
Comments
0x0000
rjmp
RESET
; Reset Handler
0x0001
rjmp
INT0
; IRQ0 Handler
0x0002
rjmp
PCINT0
; PCINT0 Handler
0x0003
rjmp
PCINT1
; PCINT1 Handler
0x0004
rjmp
WDT
; Watchdog Interrupt Handler
0x0005
rjmp
TIM1_COMPA
; Timer1 Compare A Handler
0x0006
rjmp
TIM1_COMPB
; Timer1 Compare B Handler
0x0007
rjmp
TIM1_OVF
; Timer1 Overflow Handler
