Atmel AVR - 2.8. Data Indirect with Post-increment; 2.9. Program Memory Constant Addressing using the LPM, ELPM, and SPM Instructions

2.8. Data Indirect with Post-increment
Figure 2-8. 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.
2.9. Program Memory Constant Addressing using the LPM, ELPM, and SPM
Instructions
Figure 2-9. Program Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word address. For
LPM, the LSB selects low byte if cleared (LSB = 0) or high byte if set (LSB = 1). For SPM, the LSB should
be cleared. If ELPM is used, the RAMPZ Register is used to extend the Z-register.
