I need to convert a hexadecimal number (2 nibbles) into a decimal number (max. 3 digits)
for example:
9Dh --> 157d
when 9Dh is placed in R0, after executing a certain routine, the number 1 (hundreds) should be in R1, the number 5 (tens) and 7 (units) should be in R2.
I wondered if I could use the DA instruction, but i'm told that this instruction can only be used after an ADD instruction...
Can someone help me out,

thanks
