I/O Direct
Relative Program Addressing,
RJMP and RCALL
Constant Addressing Using
the LPM Instruction
1006F–AVR–06/07
Figure 11. I/O Direct Addressing
Operand address is contained in 6 bits of the instruction word. n is the destination or
source register address.
Figure 12. Relative Program Memory Addressing
Program execution continues at address PC + k + 1. The relative address k is -2048 to
2047.
Figure 13. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word
address (0 - 511), the LSB selects low byte if cleared (LSB = 0) or high byte if set
(LSB = 1).
