In an additional aspect, a reduced-pincount Universal SPI Interface is provided that provides the same universal interface, but using fewer external output pins. The Universal SPI Interface includes multiple latches, buffers, and in an alternative embodiment, a multiplexer, configured together such that a Universal SPI interface is provided that can be readily reconfigured using only input signals to provide compatibility across multiple bus interfaces."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Universal SPI (serial peripheral interface)","description":"A Universal SPI Interface is provided that is compatible, without the need for additional interface logic or software, with the SPI bus, existing DSA and other serial busses similar to (but not direct","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9658971","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
