  53           implements a hardware byte swapper using a 32-bit datum.
  54           This endian mapping mode is called "data invariance" and
  55           has the effect of scrambling the addresses and formats of data
  56           accessed in sizes other than the datum size.

  78           disabled, it will steal the MMC cards away - rendering them
