Nios/bcd8

Binary-coded decimal is a method to represent decimal numbers encoded into binary. It uses each group of 4 bits (which can normally represent numbers from 0 to 15) to represent one decimal digit (of values 0 to 9).

Write a function that converts a number into its BCD representation. You are guaranteed that the input number will be between 0 and 99999999.

0x10

# A test case to test your function with
.global _start
_start:
    movia r4, 10     # First parameter is always in r4
    call bcd
    br _start        # End of testing code

# Convert a number to BCD representation
