Testing Notes
Computational overhead:
- MR:~2-3ms to compute a move
- Subtraction, assignment, followed by comparison/branch: ~2ms
- PR 5 character echo: ~2-3ms --> serial communication is asynchronous from the MCode
- :RESET_PG seems to be working OK (Ernesto mentioned that it used to take up to 2 seconds)
