follow the same rules specified in EHCI for programming the S-mask and C-mask for downstream
Hub-based transaction translators.
Once periodic transfers are exhausted, any stored asynchronous transfer will be moved. Asynchronous
transfers are opportunistic in that they shall execute whenever possible and their operation is not tied to
H-frame and B-frame boundaries with the exception that an asynchronous transfer can not babble through
the SOF (start of B-frame 0).
16.9.1.5.2
The start and complete split operational model differs from EHCI slightly because there is no bus medium
between the EHCI controller and the embedded transaction translator. Where a start or complete-split
operation would occur by requesting the split to the HS hub, the start/complete split operation is simple an
internal operation to the embedded transaction translator.
handshakes are emulated from internal state instead of actual handshakes to HS split bus traffic.

The following Universal Serial Bus Revision 2.0 Specification items are implemented in the embedded
transaction translator:
