A MEM_TWEAK is included in this trigger to set the WBR/DUST antenna           
multiplexor to the HF position following WBR or DUST data acquisitions. HRS   
data rate is limited by availability of CPU cycles to perform data movement   
operations (i.e.  no DMA assist available due to concurrent LFDR              
activities).
