5 / 263 page Lattice Semiconductor ORCA ORSPI4 Data Sheet 5 Figure 2. System Model for SPI4 Interface The details of the interface are specified in the OIF document “Implementation Agreement OIF-SPI4-02.0” (www.oiforum.com). That specification is based on the system model shown in the previous figure, which, in turn, is based on the Open System Interconnect (OSI) reference model. In the system model, a “transmit interface” sends address, start and end of packet signals and error control information from a Link Layer device to a PHY device and receives flow control (status) information from the PHY device. In the other direction, a “receive interface” at the Link Layer receives data from a PHY device and sends status information to the PHY device. While this convention provides a clear framework for defining the system level functions, a clean separation between Link Layer and Physical Layer functionality is not often seen in actual implementations. The ORSPI4 FPSC SPI4 blocks implement the basic functions defined in the standard and also implements addi- tional options, as suggested in the standard, to configure parameters such as maximum burst size, calendar length, length of training sequence, etc. As required by the specification, the transmit and receive interfaces oper- ate completely independently.
