efficient memcpy in Cypress FX2

We are considering the Cypress FX2. Ive seen several postings about using the dual data pointers on some 8051 devices, but they don't seem to offer much advantage when you have to waste valuable time executing instructions to toggle between the two. Curiously, there's not much I can see on exploiting the auto-increment feature of the DPTRs in some 8051 variants, and in the FX2 at least, they can both be used without having one of them 'hidden'.

I need an efficient memcpy between the FX2's endpoint memory space, (treated as a FIFO), and an external location. Is this the best way? Only two instructions in the loop... Or have I missed something?

   MOV AUTOPTRSET,#03;; enable, inc 1, not 2
   MOV r7,#64        ;;count
   MOV AUTOPTR1L,#c0
   MOV AUTOPTR1H,#e7 ;; e7c0=EP1OUT buffer
   MOV AUTOPTR2L,#00
   MOV AUTOPTR2H,#40 ;; 4000=external
loop:
   MOV XAUTODAT2,XAUTODAT1
   DJNZ R7,loop

If this is correct, the memcpy figures could be MUCH better than the figures given in the benchmarks. Any input welcome.
