Datasheet
Note 13.38 The emulated link partner’s ability is based on the P0_DUPLEX pin, duplex_pol_strap_0,
and speed_strap_0, as well as on the Auto-Negotiation success. Table 13.7 defines the
default capabilities of the emulated link partner as a function of these signals. Configuration
strap values are latched upon the de-assertion of a chip-level reset as described in Section
4.2.4, "Configuration Straps," on page 45. For more information on the Virtual PHY auto-
negotiation, see Section 7.3.1, "Virtual PHY Auto-Negotiation," on page 102.
