ATmega162/V

Notes:

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

reset, see “Boot Loader Support – Read-While-Write Self-programming” on page 217.

2. When the IVSEL bit in GICR 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.
