So far, the highest number I've been able to get out of the counter
register is 0x2e8 by setting div == 16 and playing with the pwm.

If I set div == 8, then I can't get much above 0x10b.

I have no idea what's going on either.

I tried writing 0x80 to 0x508 (which is supposed to turn the whole
thing on), but the only bits that seem to stick are 0x7, so I have no
idea what's going on.
