Abstract: A serial peripheral interface (SPI) host port is disclosed that enables a host external to a processor to access the processor's memory-mapped resources using SPI memory command protocol. An exemplary processor can include a system interconnect connected to memory-mapped resources and a SPI host port connected to the system interconnect. The SPI host port is configured to use SPI memory command protocol to access memory-mapped resources of the processor for the host external to the processor.
