– Some applications may not require transaction tracking up to a maximum of 16 periodic data
pipes. The option to limit the tracking to only 4 periodic data pipes exists in the by changing
the configuration constant VUSB_HS_TT_PERIODIC_CONTEXTS to 4. The result is a
significant gate count savings to the core given the limitations implied.
