The DC2799A Demo Board offers local side interfaces with the host SPI master as 4 different SPI slave devices. These slave devices support SPI modes (0,0) or (1,1) where (CPOL, CPHA). Three of the slave devices are associated with the remote side devices (SS1, SS2, SS3) and the fourth device (SSC) is used to configure the DC2799A’s LTC4332 SPI extenders. The DC2799A provides a remote side interface that implements an SPI master with 3 different slave selects. The remote side master supports all four SPI modes and a unique mode may be associated with each slave select.
