XTF functions
Output packet:
- for AM use all XTRP 21 bits as input to LUT to get 12-bit SuperStrip data, and add Layer=5 to tag word. Another 21-in /12-out LUT defines which phi wedge to send a given road
- to Track Fitter send the original XTRP data
Input data are logged in Spy Buffer
Reformatted data and list of enabled wedges logged in Spy Buffer
But: Will not have 12 independent Spy Buffers on outputs
