Somebody did that a few years ago as demos on H8 in fact various
H8 platforms including an IDE interface, one for USB, one for

Some of the code for command parser was a bit spaghetti, but he gives
circuits and code that may be a starter for ideas. I would suggest building
the code from the ground up though.
