How shift register may be employed to receive data ?

Question

with the most significant bit first and later with least significant bit first

Answer 1

If your data is coming in in serial form, just pipe it into a shift register. When you get to a word break, transfer the data out of the shift register in parallel form, clear the register and start the next work.

Order (MSB or LSB first) is in whatever order the data is in. Doesn't really matter.
