1). If ELPM is used, LSB of the RAM Page Z register (RAMPZ) is used to select low or
high memory page (RAMPZ0 = 0: Low Page, RAMPZ0 = 1: High Page).
Figure 17. Direct Program Memory Addressing
Program execution continues at the address immediate in the instruction words.
Figure 18. 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).
