AT91SAM7S SCC port used as an SPI port

    I once looked at the SAM7 parts for a project where I needed two SPI
    ports and very low power. I was told by the vendor that the SCC port
    could be used as an SPI port. Reading the data sheet does not make
    this obvious. I guess I could program the SCC port for I2S operation
    and use the frame sync signal like a select. This might work with the
    SPI device in slave mode and the SCC in master mode.

    Has anyone done something similar? Am I barking up the wrong tree?

    This is not a project that I can use a different processor for. The
    SAM7 is the selected part and I need to use it as best I can.

    I suppose I could always bit bang the "fake" SPI port, but that would
    likely make the port run slowly and suck up a lot of CPU cycles.
