Reserved bits. Write as 0.
Set to 1 when this register is written, regardless of the value written. Cleared by the uDMA when no additional
ready descriptors remain in the transmit ring. Also cleared when ether_en transitions from asserted to
de-asserted.
Reserved bits. Write as 0.
Reserved bits. Write as 0.
Enables the debug input pin mac_freeze. When set, the input has an effect. When cleared (0, reset value)
the input pin has no effect.
Reserved bits. Write as 0.
