will handle all link negotiations, responses, and transfers needed for the active protocol. Packet ready flags may be used to
indicate the presence of data within the buffer.

The simplest form of translation is where both ports regard the SerB as an end-point memory. Each port may write data
This is similar to the sRIO translation configuration except the SerB isolates the two ports. The device on S-Port 1 is not
