59 / 458 page  High Performance Two Port 10/100 Managed Ethernet Switch with 32-Bit Non-PCI CPU Interface Datasheet SMSC LAN9312 59 Revision 1.2 (04-08-08) DATASHEET register. When Auto-negotiation is enabled and the MANUAL_FC_x bit is cleared, the switch port flow control enables during full-duplex are determined by Auto-negotiation. Note: The flow control values in the Port x PHY Auto-Negotiation Advertisement Register (PHY_AN_AD V_ x) an d Vi rtual PHY Au to -N egotia tio n Advertisement Register (VPHY_AN_ADV) are not affected by the values of the manual flow control register. Refer to Section 7.2.5.1, "PHY Pause Flow Control," on page 92 and Section 7.3.1.3, "Virtual PHY Pause Flow Control," on page 98 for additional information on PHY and Virtual PHY flow control settings respectively. Note 6.1 If Auto-negotiation is enabled and complete, but the link partner is not Auto-negotiation capable, half-duplex is forced via the parallel detect function. Note 6.2 For the Port 1 and Port 2 PHYs, these are the bits from the Port x PHY Auto-Negotiation Advertisement Register (PHY_AN_ADV_x) and Port x PHY Auto-Negotiation Link Partner Base Page Ability Register (PHY_AN_LP_BASE_ABILITY_x). For the Virtual PHY, these are the local/partner swapped outputs from the bits in the Virtual PHY Auto-Negotiation Advertisement Register (VPHY_AN_ADV) and Virtual PHY Auto-Negotiation Link Partner Base Page Ability Register (VPHY_AN_LP_BASE_ABILITY). Refer to Section 7.3.1, "Virtual PHY Auto-Negotiation," on page 96 for more information.
