Hi,
We will get back to you.

Hi,
The details of the pin functionality is provided in the "Table 17. Pin Function Descriptions" in our data sheet.

Table 17 says "If unused, do not connect" for most of the TX pins, which is good. But does that mean that the IP and firmware support the TX data lines being disconnected? My concern is that it will fail to boot or calibrate because its expecting activity on that interface.
Hi,
Please follow the guideline in the datasheet and userguide, it should not cause any failure.

Rahul
