Document Table of Contents Programmable Termination Modes

Termination modes are programmable. However, the differential impedance values are fixed (as per the Ethernet standard specifications).

The transceiver RX is AC-coupled on-chip. This on-chip AC-coupling capacitor cannot be bypassed, and DC-coupling protocols are not supported. For AC coupling requirement details, refer the Device Family Pin Connection Guidelines "E-Tile Pins" table.

For more details on Register Read/Write support and programming, refer to PMA Register Map and PMA Attribute Codes to configure these parameters.
