it can work in "bitbang mode" that resembles parallel port read write,
and "mpsse" multi purpose serial engine than can clock in/out some
series of bytes so you can build a serial bus adapter (i.e. spi, i2c,
etc) that is faster than bitbanging the bus.

note voltages on your target and absolute maximum ratings of the chip.

note usb latency that limits the possible operations speed.

have fun! :-)
