[Tinyos-help] Question about I2C

Even though I've reviewed those archives, but I have the following doubt.  
In the MSP430I2CC.nc file contained the primitives for setting the operation 
modes. Start is generated by the I2CPacket component, whenever read or write 
is made. In the StdControl.start a call to USARTControl.setModeI2C is made  
where is configurate for to work like a master.  My question is in which 
moment it is suitable to make the call for to configurate in slave and to 
assign the OwnAddress??.  After knowing clearly this, when recognizing tmote 
its direction would generate a ACK immediately, and would begin the 
reception? 
If this is correct, these had to be processed byte to byte and which events 
are generated when information is received??.

Thank you very much.
