Use the SETB instruction and set it bit in byte 20H high.

Part 2: Add to the code to transfer each bit in RAM byte 20H to P1 keeping bit integrity. (D0 of 20H -> P1.0, etc)

Solution

org 00h

setb 00h

mov r2,#08

mov r0,#00h

mov dptr,#0090h

above: mov a,@r0

setb

movx @dptr,a

inc dptr

inc r0

djnz r2, above

here: sjmp here
