8-bit HEX to BCD convertor



This subroutine converts 8 bit Hexadecimal number into its equivalent BCD value. The number to be converted should be in the Accumulator. The output BCD number is stored in R0 & R1. R0 is used to save the MSB i.e. the hundreds place & R1 stores the LSB i.e. the Tens & Units place.

hextobcd:

mov r0,#00h
mov r1,#00h
cjne a,#00h,c1_hextobcd //If number is not 0 then continue
ret

c1_hextobcd:

clr c
mov b,#100 //First divide by 100
div ab
mov r0,a //save MSB in R0
clr c
mov a,b
mov b,#10 //Divide by 10
div ab
swap a
mov r1,a //save the tens place in the Higher nibble of R1
mov a,b
orl a,r1
mov r1,a // save the tens place in the Lower nibble of R1
ret
