... The hub provides 1 Transaction Translator (TT) that is shared by both downstream ports (defined as Single-TT configuration). The TT contains 4 non-periodic buffers. 4.1.1 Hub Configuration The USB2412 only supports internal defaults with the exception of the non-removable strap option (NON_REM[1:0]). The hub internal default settings are as follows: Internal Default Configuration without any over-rides Strap options enabled ...
