Data Indirect with Post-

increment

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.

Constant Addressing Using

the LPM and SPM Instructions

Figure 18. Code Memory Constant Addressing

Constant byte address is specified by the Z-register contents. The 15 MSBs select word

address (0 - 16K). 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.

Indirect Program Addressing,

IJMP and ICALL

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).
