The interrupts are enabled and switched to im 1. Someone will have to write
an im 1 clock to test whether the interrupt actually runs 200 (or 174) times
per second when the calculator is off. It wouldn't be too hard to port
David Philips' clock, if someone has the time.
Either that or we could get a little help from the magnanimous TI knowledge
