* Minimal simulation of the MOS 6526 CIA chip.
* Depending on what CIA it is (1 or 2), some registers do different things on the C64.
* This implementation provides a working keyboard matrix, TOD clock, and the essentials of the timer A and B.
* TODO: timer IRQ triggering, more timer control bits.
* TODO: timer IRQ triggering, more timer control bits. Validate that the timerA/B timing is cycle correct.
