Since big-endian or MSB-to-LSB bit order is most commonly used, and since this issue tends to create LOTS of confusion, I maintain that the preferred course is to read (and frown upon) LSB-to-MSB order, read (and prefer) MSB-to-LSB order, and ALWAYS write MSB-to-LSB order. When performance issues arise, choose best berformance for big-endian or MSB-to-LSB bit order, and take the hit on LSB-to-MSB order.
