[edit] Interrupts

The Generic Clock can perform three interrupts depending on the value of the A register:

A Behavior
0 The B register is read, and the clock will tick 60/B times per second. If B is 0, the clock is turned off.
1 Store number of ticks elapsed since last call to 0 in C register.
2 If register B is non-zero, turn on interrupts with message B. If B is zero, disable interrupts.

When interrupts are enabled, the clock will trigger an interrupt whenever it ticks.
