9.38.2 Symbolic Operand Modifiers
---------------------------------
The RL78 has three modifiers that adjust the relocations used by the
linker:
'%lo16()'
When loading a 20-bit (or wider) address into registers, this
modifier selects the 16 least significant bits.
movw ax,#%lo16(_sym)
'%hi16()'
When loading a 20-bit (or wider) address into registers, this
modifier selects the 16 most significant bits.
movw ax,#%hi16(_sym)
'%hi8()'
When loading a 20-bit (or wider) address into registers, this
modifier selects the 8 bits that would go into CS or ES (i.e. bits
23..16).
mov es, #%hi8(_sym)
