Register-to-Memory—Only control alterable addressing modes or the predecrement
dr field—Specifies the direction of the transfer.
Register List field—Contains the register select mask. If a register is to be moved, the
0 — Move the listed registers from memory to the floating-point unit.
1 — Move the listed registers from the floating-point unit to memory.
addressing mode can be used as listed in the following table:
corresponding bit in the list is set; otherwise, it is clear. At least one register must
be specified.
*Only if a single floating-point control register is selected.
**Only if the floating-point instruction address register is the single register selected.
