BCM2709 SPI0 Device

The BCM2709 has a single master mode SPI controller that supports 3 wire, 2 wire and LoSSI modes of operation. It also has 2 auxiliary SPI masters which do not support DMA mode (see SPI1/2 below).

The main SPI0 controller supports polled, interrupt and DMA modes and includes 3 chip selects although only CS0 and 1 are available on the 26 or 40 pin header.

By default SPI0 can appear on GPIO pins 7 to 11 (CS1, CS0, MISO, MOSI, SCLK) using alternate function 0 or on GPIO pins 35 to 39 (CS1, CS0, MISO, MOSI, SCLK) using alternate function 0, only pins 7 to 11 are available on the header.
