I am in the late stages of trudging through an interrupt-driven I2C
interface for the 2106..  I believe it's the same hardware.

The I2C system interrupts you only on a 'state change'.  Therefore, you
have to read/write the data port at the right time to result in an
interrupt.  In my case, I had to set the STA flag, write bytes, then set
the STO flag.  I got an interrupt after setting the STA flag and after
each write.

I can see how setting the interrupt bit high will force the issue but
then your status register will probably only give you an 0xf8.

Good luck.
