What I use is 88 e1111phy chip, want to set a phy rate of 0 to change working mode and register, but use phy_write interface written after register, reoccupy phy_read read just wrote 0 registers, found the register values and didn't write is the same as before,
What is this?
Software reset is asserted (0.15) Register
Power down transtions from power down to normal operation
Manual on what those words mean?
Can we need to register if set the register zero reset, the function of the Settings to take effect?
