Stresses greater than those listed under Absolute Maxi- mum Ratings may cause permanent damage to the de-vice. This is a stress rating only; operating of the device at any condition above these indicated in the operational sectionsof these specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The Z16COl/CO2 CPU are members of the 16-bit processor and controller family. Designed using a RISC-like Load/Store architecture, the CPU can operate in either system or normal modes, permitting privileged operations and improving operating system organization and implementation.

To boost the Z16COl/CO2  main CPU's performance capability, the processor core includes hardwired control and is a 16-bit real-time processor functioning at register access speeds. Register flexibility is created by grouping or overlapping multiple registers, and by allowing extended register file capabilities as the system expands. Easy extended register file control is accomplished through a single instruction stream communication.

The Z16COl/CO2  CPUsupportsthreetypesof interrupts (non-maskable, vectored, and non-vectored) and four traps (system call, extended process architecture instruction, privileged instructions, and segmentation trap). The vectored and non-vectored interrupts are maskable.
 
The Z16COl/CO2  processor's resources include seven data types that range from bits to 32-bit long words, and byte and word strings, plus eight user-selectable addressing modes. The nine basic instruction types can be combined with various data types and addressing modes to form a powerful set of 414 instructions.

The extended processing architecture features provide a modular approach to expanding both the hardware and software capabilities of the Z16COl/CO2.
