Interrupts
Table 6-25.
This section describes the specifics of the interrupt handling as performed in Atmel
ATA6612/ATA6613. For a general explanation of the AVR
and Interrupt Handling” on page
The interrupt vectors in Atmel ATA6612 and ATA6613 are generally the same, with the follow-
ing differences:
• Bit 5, 2..0 - WDP3..0: Watchdog Timer Prescaler 3, 2, 1 and 0
WDP3
• Each Interrupt Vector occupies two instruction words in ATA6613, and one instruction word
• In Atmel
in Atmel ATA6612.
the Interrupt Vector start address is affected by the IVSEL bit in MCUCR.
The WDP3..0 bits determine the Watchdog Timer prescaling when the Watchdog Timer is
running. The different prescaling values and their corresponding time-out periods are
