CC430F5137: High current consumption in LPM3 compared to CC430F5147

Following code cause high current consumption (100uA) in LPM3 with CC430F5137. Same code with CC430F5147 has a more normal consumption of 4.3uA. It is the combination of RF1 in WOR and TA0. Disabling either and CC430F5137 drops down to 4.3uA. Also removing //TA0CCTL0 |= CCIE; (*1) drops current down to 4.3uA.
What am I missing?
