I have assembled subroutine that it's job is to convert a 2 digit BCD number in Hex to an 2 digit Decimal , and also to display this 2 digit number on the lcd (thus to add 30h to them).
I written the following code to do that , but somewhy It doesn't work properly , if someone could please check it , or better , have a diffrent code to do that , I would appreciate the help.

Input ->Acc
output1 ->MSB = Acc
output2 ->LSB = R3
temporarly registers R4.

BTD: MOV R3,A
MOV R4,A
ANL A,#0F0H
SWAP A
MOV B,#06H
MUL AB
XCH A,R4
ANL A,#0FH
ADD A,R4
DA A
XCH A,R3
ANL A,#0F0H
ADD A,R3
BTD1: MOV R3,A
ANL A,#0FH
ADD A,#30H
XCH A,R3
SWAP A
ANL A,#0FH
ADD A,#30H
RET
