There are a few ways...
* The most flexible (but also the slowest) way is to use sprintf().
* You can use the built-in BCD functions (or make your own). They basically deal
with hexadecimal numbers but don't use A-F, so a normal register can contain
0000-9999. Then you just use whatever way of printing hexadecimal you want.
* The last one is to write your own routine for plotting a hex number as a
decimal. The easiest (but not fastest) way is to repeatedly divide by 10 and
write the remainder to a string until the division becomes zero.
