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 Figure 18. Code Memory Constant Addressing
the LPM and SPM Instructions
$3FFF
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.

Program execution continues at address contained by the Z-register (i.e., the PC is
loaded with the contents of the Z-register).
