Interrupts

This section describes the specifics of the interrupt handling as performed in ATmega162. For a

general explanation of the AVR interrupt handling, refer to “Reset and Interrupt Handling” on

page 14. Table 24 shows the interrupt table when the compatibility fuse (M161C) is unpro-

grammed, while Table 25 shows the interrupt table when M161C Fuse is programmed. All

assembly code examples in this sections are using the interrupt table when the M161C Fuse is

unprogrammed.
