TLE 8102 SG Smart Dual Channel Powertrain Switch Electrical and Functional Description of Blocks 5.6 SPI Interface The diagnosis and control interface is based on a serial peripheral interface (SPI). The SPI is a full duplex synchronous serial slave interface, which uses four lines: SO, SI, SCLK and CS. Data is transferred by the lines SI and SO at the data rate given by SCLK. The falling edge of CS indicates the beginning of a data access.

TLE 8102 SG Smart Dual Channel Powertrain Switch Electrical and Functional Description of Blocks SO - Serial Output: Data is shifted out serially at this pin, the most significant bit first. SO is in high impedance state until the CS pin goes to low state. New data will appear at the SO pin following the rising edge of SCLK. Please refer to Section 6 for further information. 5.6.2 Daisy Chain Capability The SPI of TLE8102SG is daisy chain capable.
