LDS - Load Pointer Using DS
Usage: LDS dest,src
Modifies flags: None
Loads 32-bit pointer from memory source to destination register
and DS. The offset is placed in the destination register and the
segment is placed in DS. To use this instruction the word at the
lower memory address must contain the offset and the word at the
higher address must contain the segment. This simplifies the loading
of far pointers from the stack and the interrupt vector table.
