Here is the sentence I concluded that it could be connected to i2c: 6. Register Control The CH7009 is controlled via a serial port. The serial port bus uses only the SPC clock to latch data into registers, and does not use any internally generated clocks so that the device can be written to in all power down modes. The device retains all register states. I somehow thought, because its a synchonous serial bus, it could be a i2c. Sorry that I wasted so much time of you, bye, od -- od at fli4l.de * http://www.fli4l.de/ * the on(e) disk router
