These bits contain the destination address for the
Memory Move.
If the destination address is in the 64-bit address space,
the bits will be contained in the
register.
5.7 Load and Store Instructions
The Load and Store instructions provide a more efficient way to move
data from/to memory to/from an internal register in the chip without using
the normal memory move instruction.
The load and store instructions are represented by two Dword opcodes.
The first Dword contains the
and
register values. The second Dword contains the
value. This is either the actual memory
location of where to load/store, or the offset from the
, depending on the value of bit 28 (DSA Relative).
For load operations where the data is read from the 64-bit address
space, the upper Dword of address resides in the
register. For store operations where the data is written
to the 64-bit address space, the upper Dword of address resides in the
Memory Move Write Selector (MMWS)
register.
A maximum of 4 bytes may be moved with these instructions. The
register address and memory address must have the same byte
alignment, and the count set such that it does not cross Dword
boundaries. The memory address may not map back to the chip,
