PPI receive 12 bits

Recently I made a board with a BF518 that used the PPI with a 12-bit interface.  I used the pins corresponding to D0-D11 and it worked fine except that I had to shift the data because it was zero-filled in the high bits.

 

Is it possible to connect to D4-D15 to avoid having to shift the data, or will the DMA still move the data in the low part of the word and zero fill the rest?

 

Thanks,

Mark
