I2C控制

Subject: SLG46826 real-time control via the I2C bus...

Your inquiry/feedback:
Want to know if the I2C interface to the SLG46826 is useful as a way to command the I/O pins after the device is programmed.
If so, how does one set up the part to do it?
Can I read a command sent from a host devices via the I2C bus, and interpret the command to toggle a pin?

Thanks
