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.
