7.4.1.2 Single Device: Standard SPI Interface
Figure 7-25 shows the minimum pin interface for applications using a standard SPI protocol.
Figure 7-25 Standard SPI Protocol Pin ConfigurationThe CONVST/CS, SCLK, SDI, and SDO-0 pins constitute a standard SPI port of the host controller. The RST pin can be tied to DVDD. The RVS pin can be monitored for timing benefits. The ALARM/SDO-1/GPO pin may not have any external connection.
