An effective address (EA) is formed by adding a displacement to a base address. The displacement is
obtained by sign-extending the 16-bit D field to 32 bits. The base address is 0 when the RA field is 0, and is
the contents of register RA otherwise.
The contents of a series of consecutive registers, starting with register RS and continuing through GPR(31),
are stored into consecutive words starting at the EA.
Registers Altered
• None
Programming Note
This instruction can be restarted, meaning that it could be interrupted after having already stored some of the
register values to memory, and then re-executed from the beginning (after returning from the interrupt), in
which case the registers which had already been stored prior to the interrupt will be stored a second time.
