im not to sure exactly what you want to do here:

"mov a,#0Fh" is the same as "mov a,#1111b" and vice versa.

The only thing i can think of is if you wanted to display binary charchters on an LCD display for example as its friday and iam bored i will write some code :) :


;clear registers r0 to r7

main:

mov a,#0Fh ;set acc to ascii value to be converted

jb acc.0,$set_r0

$check_bit1
jb acc.1,$set_r1

$check_bit2
jb acc.2,$set_r2

$check_bit3
jb acc.3,$set_r3

$check_bit4
jb acc.4,$set_r4

$check_bit5
jb acc.5,$set_r5

$check_bit6
jb acc.6,$set_r6

$check_bit7
jb acc.7,$set_r7

$done
;send r7 to r0
;bytes sent will be 00,00,00,00,01,01,01,01
jmp $

$set_r0
mov r0,#01h
jmp $check_bit1

$set_r1
mov r1,#01h
jmp $check_bit2

$set_r2
mov r2,#01h
jmp $check_bit3

$set_r3
mov r3,#01h
jmp $check_bit4

$set_r4
mov r4,#01h
jmp $check_bit5

$set_r5
mov r5,#01h
jmp $check_bit6

$set_r6
mov r6,#01h
jmp $check_bit7

$set_r7
mov r7,#01h
jmp $done
