Figure 17. 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.
Figure 18. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word
address (0 - 8K). 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.
Figure 19. Indirect Program Memory Addressing
Program execution continues at address contained by the Z-register (i.e., the PC is
loaded with the contents of the Z-register).
