0(External MII) Manual Flow Control Register
(MANUAL_FC_MII). When latched low, flow control
is disabled on RX/TX. When latched high, flow
control is enabled on RX/TX. See
Port 0(External MII) Manual Flow Control Enable
Strap: Configures the default value of the
MANUAL_FC_MII bit in the

When latched low, flow control is determined by
Virtual Auto-Negotiation. When latched high, flow
control is determined by TX_FC_MII and
RX_FC_MII bits in the
Flow Control Register
