This method works fine for me using an 877, but I am doing this through
HiTech C, and I use db rather than de.

It seems ok, I use the snippet below in a running s/w
the only difference i see is the DE vs. DW but that should be ok.

       ORG     0x2100  ; 256 bytes of eeram
               DW      0x31
               DW      0x80    ; etc..

So it should work, how about the WREN ?
