(1)
An external 3.01kΩ ±1% resistor must be connected between this pin and VSS. No external voltage should be applied to this pin.
(2)
The functionality of these pins is controlled by the SERDES0_LN0_CTRL_LANE_FUNC_SEL register.
(3)
The SERDES0 interface is not supported by the ALX packaged devices. See AM243x_ALX Package - Unsupported Interfaces and
Signals for additional details.
