The gateway controller retrieves operation code (opcode) from a signal from the SPI bus and an address number from the signal; the gateway controller further compares the retrieved opcode with a restrict opcode, the retrieved address number with a restrict address number. When either the retrieved opcode matches the restrict opcode, or the retrieved address number matches the restrict address number, the gateway controller blocks the signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"SIO device with SPI bus gateway controller for write protection","description":"A serial input/output (SIO) device with a serial peripheral interface (SPI) bus gateway controller.
