Figure 18. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word
address (0 - 1K), the LSB selects low byte if cleared (LSB = 0) or high byte if set (LSB =
1).
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).
Figure 20. Relative Program Memory Addressing
Program execution continues at address PC + k + 1. The relative address k is -2048 to
2047.
