Description:
1. This instruction transfers XDm contents to memory at address indicated by Rn.
2. This instruction transfers contents of memory at address indicated by Rm to XDn.
3. This instruction transfers contents of memory at address indicated by Rm to XDn, and adds 8
to Rm.
4. This instruction subtracts 8 from Rn, and transfers XDm contents to memory at address
indicated by resulting Rn value.
5. This instruction transfers contents of memory at address indicated by (R0 + Rm) to XDn.
6. This instruction transfers XDm contents to memory at address indicated by (R0 + Rn).
7. This instruction transfers XDm contents to XDn.
8. This instruction transfers XDm contents to DRn.
9. This instruction transfers DRm contents to XDn.
