Registers for the MOS Tehnology Complex Interface Adapter 6526

The CIA served as an I/O port controller for the 6502 family of microprocessors, providing for parallel and serial I/O capabilities as well as timers and a Time-of-Day (TOD) clock. The device’s most prominent use was in the Commodore 64 and Commodore 128(D), each of which included two CIA chips.
