two, analog signal accumulators, which means two analog gyros
two, I2C buses (with two sidecars)
two, SPI buses (with two sidecars) plus chip selects (on Dig I/Os)
serial communications through the cRIO serial port

One inaccuracy here. The SPI engine is routable to any DIO pins on either module... there is only one of them. The hardware supports streaming with 512 word buffers on both the send and receive side and buffer status interrupts (such as half full), but that is not implemented in the library yet. WPILib for LabVIEW supports single sample SPI transfers and WPILib for C++ has no support. This is a low priority system. Right now it seems there is little demand for it.
Stop. Breathe. Relax. QUIT STATING STUFF THAT YOU DON'T KNOW TO BE TRUE.
