FMOVEM Move Multiple Registers
Registers -> Destination
Source -> Registers
Selected registers are transferred to or from consecutive memory starting at <ea>
| Assembler Syntax: | FMOVEM.X <register list>,<ea> |
| FMOVEM.X Dn,<ea> |
| FMOVEM.X <ea>,<register list> |
| FMOVEM.X <ea>,Dn |
<register list> is a list (static mask) of any combination of the eight floating point data registers.
Dn is a dynamic mask in which the least significant 8 bits specify the registers to be transferred.
