Help: ICE_FLAGS_TGO

Use bit0 (or ext SMB if XGO and TGO) to trigger start


Use bit0 (or ext SMB if XGO and TGO) to trigger start.  The rising edge of 
this signal should be coincident with the data clock rising edge of the first 
sample of interest.  If XSOE is enabled, the output signal will go high
on the rising edge of the 2nd sample.  To slave another channel or card
to this signal, make sure to add both SGO and TGO to tell the slave that
the enable signal is one sample late.
