How does the ShortStack Micro Server communicate with my host processor?
It communicates with your host processor using either a Serial Communications Interface (SCI) or a Serial Peripheral Interface (SPI). The ShortStack SCI interface is a half duplex asynchronous serial interface with 1 start bit, 8 data bits, and 1 stop bit. The ShortStack SPI interface is a half-duplex synchronous serial interface between the ShortStack Micro Server and the host processor, with the Micro Server acting as the SPI master and the host acting as the SPI slave.
