/* XXX: Seems, the _SFR_MEM_ADDR() is worse. In this case it works only
with ports, which have the address higher then SREG. There is no
method to obtain the address suitable for LDS/STS instruction. Now
this test cases are commented. Second, the _SFR_ADDR() is not defined.
This is mismatch to C behavior (_SFR_ASM_COMPAT, __SFR_OFFSET = 0). */
