20.4.5.2. Serial Transfers

“National Semiconductor Microwire Protocol” describes the Microwire serial protocol in detail, including timing diagrams and information about how data are structured in the transmit and receive FIFO buffers before and after a serial transfer. The Microwire protocol operates in much the same way as the SPI protocol. There is no decode of the control frame by the SPI slave device. †
