22.2.2 BiSS Supported Modes

The BiSS module supports BiSS/BiSS-C and SSI modes. There are a few differences between BiSS and SSI, but the main considerations are speed and whether control communication is needed. BiSS can operate at a maximum of 10 MHz, while SSI can operate at a maximum of 1.5 MHz. BiSS can communicate data every cycle and can also communicate control data or commands. SSI only communicates data each cycle. Setting the CFGCHx bits in the BiCHCON register for each channel configures the channel in the desired BiSS operating mode.
