ATmega323(L)

1457G–AVR–09/03

The 2K bytes data SRAM can be easily accessed through the five different addressing

modes supported in the AVR architecture.

The memory spaces in the AVR architecture are all linear and regular memory maps.

A flexible interrupt module has its control registers in the I/O space with an additional

Global Interrupt Enable bit in the Status Register. All interrupts have a separate Interrupt

Vector in the Interrupt Vector table. The interrupts have priority in accordance with their

Interrupt Vector position. The lower the Interrupt Vector address, the higher the priority.
