Revision 0; 8/11

Example(s): MOVE A[0], A[3] ; A[0] ← A[3]

MOVE DP[0], #110h ; DP[0] ← #0110h (PFX[0] register used)

; MOVE PFX[0], #01h (smart-prefixing)

; MOVE DP[0], #10h

MOVE DP[0], #80h ; DP[0] ← #0080h (PFX[0] register not needed)

Special Notes: Proper loading of the PFX[n] registers, when for the purpose of supplying 16-bit immediate data

or accessing 2-cycle destinations, is handled automatically by the assembler and is therefore an

optional step for the user when writing assembly source code. Examples of the automatic PFX[n]

code insertion by the assembler are demonstrated below.
