I would like a better understanding of the energy detect register settings and the bit functions. In the application, an ethernet network will not normally be connected, so the goal is to have the PHY stay powered down and generate as little EMI as possible.
Energy detect burst disable: "By default, Energy Detect (ED) transmits a burst of 4 ED data pulses each time the CD is powered up."
What is the CD? What is the impact of disabling this?
Energy Detect Error Threshold: What is an energy detect error event? What is the typical setting for these four bits?
Energy Detect Data Threshold: What is an energy detect event? What is the typical setting for these four bits?
When the device "takes actions," what actions are taken?
