Interrupts
Interrupt Vectors in AT90PWM81
This section describes the specifics of the interrupt handling as performed in AT90PWM81. For a general
explanation of the AVR interrupt handling, refer to
Table 8-1.
Notes:
Table 8-2
IVSEL settings. If the program never enables an interrupt source, the Interrupt Vectors are not used, and
Vector
No.

1. When the BOOTRST Fuse is programmed, the device will jump to the Boot Loader address at reset, see
2. When the IVSEL bit in MCUCR is set, Interrupt Vectors will be moved to the start of the Boot Flash

“Boot Loader Support – Read-While-Write Self-Programming” on page
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.
