12.3.2 Stack and Index Register Instructions
The following table summarizes the instructions available for the 16-bit index registers (X and Y)
and the 16-bit stack pointer.
The exchange D with X (XGDX) and exchange D with Y (XGDY) instructions provide a simple way
of getting a pointer value from a 16-bit index register to the D accumulator which has more powerful
16-bit arithmetic capabilities than the 16-bit index registers. Since these are bidirectional exchanges,
