Example:
ldi ZL, byte3(Table_1<<1) ; Initialize Z-pointer
out RAMPZ, ZL
ldi ZH, byte2(Table_1<<1)
ldi ZL, byte1(Table_1<<1)
elpm r16, Z+ ; Load constant from Program
; memory pointed to by RAMPZ:Z (Z is r31:r30)
...
Table_1:
.dw 0x3738 ; 0x38 is addressed when Z
LSB
= 0
; 0x37 is addressed when Z
LSB
= 1
