Question about Strap configuration in datasheet page36:
When they use this part at SGMII
My understanding is they should use Rhi = 4 kΩ and Rlo = 10 kΩ on RX_D0 and RX_D1 , RX_D2 and RX_D3.
Is my understanding correct ?
In this case ,do these resisters affect to diffrential signal ? If you hane recommend layout pattern of these resisters ,please let us know it ?

Question about description of Unused Pins in datasheet page8:
Which(A or B) below description is correct ?
A:
“Even though a device may have internal pullup or pulldown resistors, a good practice is to terminate unused
inputs rather than allowing them to float.”
B:
“Except for VDDA1P8 pins, if they are not used then they should be left floating.”
If A is correct, should pin of Type: PD or PU be connected directly to VDD or GND ?
When they don’t use INT / PWDN, please let us know pin treatment.
