Lpc2000

I am trying to setup a basic i2c bus master using a lpc2105.  I need
to be able to read/write to several different devices as a master.  

Using the example code "LPC2106__Examples.zip" the chip will not give
up the bus lines after sending data.  This would be fine for an IO
expander, but not for multiple devices.  I have figured out that this
is because the code does not send a stop bit, so the slave is always
being addressed.  

I sent a stop bit following the clear interrupt (SI) command but this
only cut my message down to a couple bits (the time it took to get to
that instruction).

So what should the program flow be?  It doesn't seem logical to me at all!

Thanks.
