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