Cleared by the user code for normal I
I
Set by the MicroConverter if the interface is transmitting.
Cleared by the MicroConverter if the interface is receiving.
I
Set by the MicroConverter after a byte has been transmitted or received.
Cleared automatically when user code reads the I2CDAT SFR (see I2CDAT below).
