Hi all,

I need to shift a 5 bit number in, through and out of a byte using bit0 to
bit4 and not affect bit5 - bit7.

The best way I can think of an example is if you had two 8 bit wide
registers next to each other like the following.  The 5 bit value in byte 2
is shifted left throughout byte 1 and out.

byte1     byte2

XXX00000  xxx11111      start state
XXX00001  xxx11110
XXX00011  xxx11100
XXX00111  xxx11000
XXX01111  xxx10000
XXX11111  xxx00000
XXX11110  xxx00000
XXX11100  xxx00000
XXX11000  xxx00000
XXX10000  xxx00000
XXX00000  xxx00000      end state

Only byte 1 is important, byte 2 is just for my example.

X = can not be changed.
x = not used

Anyone have any ideas on how to do this?  I think a couple of loops and
some bit testing & setting will do it but I just can't seem to crack the
algorithm needed.

Regards
Jean-Michel.
