Datasheet
Note 13.44 The reserved bits 31-16 are used to pad the register to 32-bits so that each register is on
a DWORD boundary. When accessed serially (through the MII management protocol), the
register is 16-bits wide.
Note 13.45 The default value of this field is the result of the Auto-Negotiation process if the Auto-
Negotiation (VPHY_AN) bit of the Virtual PHY Basic Control Register
(VPHY_BASIC_CTRL) is set. Otherwise, this field reflects the Speed Select LSB
(VPHY_SPEED_SEL_LSB) and Duplex Mode (VPHY_DUPLEX) bit settings of the
VPHY_BASIC_CTRL register. Refer to Section 7.3.1, "Virtual PHY Auto-Negotiation," on
page 98 for information on the Auto-Negotiation determination process of the Virtual PHY.
Note 13.46 Register bits designated as NASR are reset when the Virtual PHY Reset is generated via
the Reset Control Register (RESET_CTL). The NASR designation is only applicable when
the Reset (VPHY_RST) bit of the Virtual PHY Basic Control Register
(VPHY_BASIC_CTRL) is set.
Note 13.47 The default value of this field is determined via the SQE_test_disable_strap_mii
configuration strap. Refer to Section 4.2.4, "Configuration Straps," on page 45 for
additional information.
