ENC624J6Net

- changed interrupt usage for Int2 instead of Int6 
    (after discussion with Matze about "best" approach)
  - see HW_INTSOURCE in hw.c for the active interrupt source
  - this build reflects changed word handling in CPLD code,
    now all addresses below $6000 are presented as Big Endian
    words, such that copies of the frames can be done with
    fast instructions like movem
