Figure 18. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word
address (0 - 2K), 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 from
-2048 to 2047.
