  • Passive processor communications interface
    Patent number: 5109494
    Abstract: A passive interface between a processor and a peripheral device is shown. The peripheral device could also be another processor. The interface allows asynchronous communication between the devices. Speed limitations are minimized as the processor has the ability within the interface to know when it can send data, and when it has received data. The number of interface pins is also minimized. Also, communication between devices can still be performed even if the devices have different data bus widths.

  • Pin selectable multi-mode processor
    Patent number: 5101498
    Abstract: A processor which has two different communications modes, a test mode, an an emulator mode is shown. These modes are selected by controlling inputs to two pins. More modes could be added with more pins. When a given mode is switched into, certain I/O pins instantly change function. Minimal hardware and software is required to implement a switch thus allowing rapid switches.
