Peter,
  I think you are correct in your assumptions.

  Your right, rambank 0 cannot be accessed using FSR/IND. It can ONLY be accessed by setting FSR to $00 and using semi direct addressing. As in "MOV xx,W" where xx is between $10 and $1F inclusive.

  This is why SX/B uses rambank 1 (FSR=$10) as the default on the SX48.
