Idle Mode Status Flag 

This status flag indicates that the serial bus activity has 
stopped. 

This bit is cleared to 0 if the serial bus are currently 
active while TEN = 1 or REN = 1. 

This bit is automatically set to 1 if both TEN and REN 
are cleared to 0 and the current system word 
communication is completed. 

Note:  If the external device stops the serial bus clock 

before the current system word is completed, 
this bit is not set. 

Note:  * The 

bit can be read or written to. Writing 0 initializes the bit, but writing 1 is ignored.
