Abstract
A serial peripheral interface achieves compatibility with devices having previous such interfaces while significantly reducing the amount of intervention required on the part of the controlling data processing device. Many serial transfers are written to a memory by the controlling device together with command and control information. The interface then executes the stored, or queued, transfers autonomously. Features such as programmable transfer length, programmable chip selects, an alterable queue pointer, and others contribute to the flexibility and usefulness of the interface.
