In the full-duplex mode, this bit should be read as 0x0 before writing to
the Flow Control register. To initiate a Pause control frame, the
Application must set this bit to 0x1. During a transfer of the Control
Frame, this bit continues to be set to signify that a frame transmission
is in progress. After the completion of Pause control frame transmission,
the MAC resets this bit to 0x0. The EMACFLOWCTL register should
not be written to until this bit is cleared.
