/* Macro 'X_lpm' extends enhanced lpm instruction for classic chips.
|

Usage:
|
|
||||||
X_lpm reg, dst
|
|
||||||
where
|
|
||||||
reg is 0..31, r0..r31 or R0..R31

dst is z, Z, z+ or Z+
|
|
||||||
It is possible to omit both arguments.
|
|
||||||
|
|
||||||
Possible results for classic chips:
|
|
||||||
lpm
|
|
||||||
lpm / mov Rd,r0
|
|
||||||
lpm / adiw ZL,1
|
|
||||||
lpm / mov Rd,r0 / adiw ZL,1
|
|
||||||
|
|
||||||
For enhanced chips it is one instruction always.
|
|
||||||
|
|
||||||
ATTENTION: unlike enhanced chips SREG (S,V,N,Z,C) flags are
|
|
||||||
changed in case of 'Z+' dst. R0 is scratch.
