I'm having some difficulties with this particular "exercise"...
If anyone can solver/explain it, it would be great! Thank you for your time and have a nice day.

 

Its quite straight forward.... Read port 2 if the enable is low ( P1.0) send the value on P0,x to P1.5... repeat!!

my problem is about how the loop will be written in assembly..Thanks for the reply though

 

What textbook do you use?

 

[01[ Read the content of Port 0 to the Accumulator.
[02] Read the content of Port 2 to a register (say R1) and add 1 to it.
[03] Perform a RLC A based on the number in R1. (Use DJNZ)
[04] The required bit to be output is now in the Carry Flag.
[05] Use the MOV bit,C and move bit to P1.5.
