Well I set this as a "break point" so if the data finishes the parameters after this instruction will reset the byte to the first one.

I know that is your desire. This is the reason for my question: Why #BH ? Why not #54H since is the tail of your queue. CJNE R0,#54H,CICLO2.

If you will use DPTR it will be interesting to see how the break point will look like.

I want to send all bits one by one trough the port p1.0

You will not be able to use P1.1-7 as time as send rotated BYTE direct to P1.
It will be wise to mask the Accumulator prior sending to P1 in order do not affect all P1 bits. Only P1.0
