Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

3 | rstpdwnmodule | Reset Power-Down Modules (RstPdwnModule) This bit is valid only in Partial Power-Down mode. The application sets this bit when the power is turned off. The application clears this bit after the power is turned on and the PHY clock is up.Note: The R/W of all core registers are possible only when this bit is set to 1b0.
