Data Indirect With Post-Increment
Figure 15. Data Indirect Addressing with Post-Increment
The X, Y or the Z-register is incremented after the operation. Operand address is the content of the X, Y or the Z-register
prior to incrementing.
Constant Addressing Using the LPM and ELPM Instructions
Figure 16. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word address (0 - 32K), LSB selects low
byte if cleared (LSB = 0) or high byte if set (LSB = 1). If ELPM is used, LSB of the RAM Page Z register - RAMPZ is used to
select low or high memory page (RAMPZ0 = 0: Low Page, RAMPZ0 = 1: High Page). ELPM does not apply to the
ATmega603.
