Program Memory with Post-increment using the LPM Z+ and ELPM Z+ Instruction
Figure 1. Program Memory Addressing with
Post-increment
Constant byte address is specified by the Z-register contents. The 15 MSBs select word address. The LSB selects low byte if cleared (LSB = 0) or high byte if set (LSB = 1). If ELPM Z+ is used, the RAMPZ Register is used to extend the Z-register.
