AT43USB353M
3307B–USB–4/04
With the relative jump and call instructions, the whole 24K address space is directly accessed.
Most AVR instructions have a single 16-bit word format. Every program memory address con-
tains a 16- or 32-bit instruction.
During interrupts and subroutine calls, the return address Program Counter (PC) is stored on
the stack. The stack is effectively allocated in the general data SRAM, and consequently, the
stack size is only limited by the total SRAM size and the usage of the SRAM. All user pro-
grams must initialize the Stack Pointer (SP) in the reset routine (before subroutines or
interrupts are executed). The 10-bit SP is read/write accessible in the I/O space.
The 1-Kbyte 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 flexi-
ble 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 at the beginning of the program memory. The interrupts have priority in accor-
dance with their interrupt vector position. The lower the interrupt vector address, the higher the
priority.
The General-
purpose
Register File
All register operating instructions in the instruction set have direct and single cycle access to
all registers. The only exception is the five constant arithmetic and logic instructions SBCI,
SUBI, CPI, ANDI, and ORI between a constant and a register, and the LDI instruction for load
immediate constant data. These instructions apply to the second half of the registers in the
register file – R16..R31. The general SBC, SUB, CP, AND, and OR and all other operations
between two registers or on a single register apply to the entire register file.
