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 12. Table 24 shows the interrupt table when the com-
patibility fuse (M161C) is unprogrammed, 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.
