SM320F2812-EP TESTSEL input and XINTCNF2 Register "Write Buffer Depth"

Hi,

We have a product with the TESTSEL input floating. The datasheet states "MUST BE CONNECTED TO GND". The products is qualified with this input floating for a reason I dont know. The HW designer has moved on to another company and can not be reached.
What could the consequenses be leaving it unconnected?

Our SW team can not see any speed gains when increasing the write buffer depth from 0 to 3. In what situation will the setting 3 gain most advantage?

BR,
