Hi:
Thank you all.
Take a byte number 0b00000001 for example ^ ^ high bit low bit
I used to think in a LE machine it will be stored as 0b10000000 low bit first
^ ^
low bit high bit
and in a BE machine will be 0b00000001 high bit first ^ ^ high bit low bit
not only the byteorder is different, but inside a byte is also different.
But actually they are the same, right? yes they are same. In fact it is termed as 'byte' order not 'bit' order. Hope this helps. Thank you.

Is there some difference of the storge between BE and LE machine inside a byte?
No. At least TTBOMK there exists no such hardware.
Using SHL/SHR would tell you - SHL normally results in a multiply by 2, SHR a divide by 2. If the byte was little endian, the results would be visa-versa
But I agree, I doubt there is any such hardware
