Display Stacking View.
Stacking conserves space in the trace view by displaying repeating
items (or item groups) as one item, along with the number of repeats.
For USB 2.0, stacking items (or item groups) can be:
• SOF
• Chirp (merges J's and Ks into one stacked display unit)
• NAK'ed (split) Transaction
For USB 3.0, stacking items (or item groups) can be:
• TSEQ
• TS1 with same Link Functionality
• TS2 with same Link Functionality
• LFPS with same Type
• LUP
• LDN
• NAK'ed Transaction
Note: Items are grouped regardless of any intervening Skip
Sequence, Electrical Idle, or Logical Idle symbols. If any of these
occur during a stream of the repeating stacking item, they are not
displayed.
