Can the AM3359 cpu have 3SPI? Has the AM3359 three SPI chip select pin? Has the AM3359 these chip select pins such as SPI0_CS0,SPI0_CS1 ,SPI1_CS0and SPI1_CS1? I want to use three SPI channel to driver three SPI chip working , I see AM3359 has only 2 SPI. I don't know how much the AM3359 CPU have chip select pins and channels to driver slave SPI devices?
