DATASHEET

Note 13.55

The Pause and Asymmetric Pause bits are loaded into the PHY registers by the EEPROM

Loader.

Note 13.56

The default value of this bit is determined by the Manual Flow Control Enable Strap

(manual_FC_strap_x). When the Manual Flow Control Enable Strap is 0, this bit defaults

to 1 (symmetric pause advertised). When the Manual Flow Control Enable Strap is 1, this

bit defaults to 0 (symmetric pause not advertised). 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. Refer to Section 4.2.4, "Configuration Straps," on page 45 for

configuration strap definitions.

Note 13.57

The default value of this bit is determined by the logical OR of the Auto-Negotiation strap

(autoneg_strap_x) with the logical AND of the negated speed select strap (speed_strap_x)

and (duplex_strap_x). Table 13.8 defines the default behavior of this bit. 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. Refer to Section 4.2.4, "Configuration Straps,"

on page 45 for configuration strap definitions.

Note 13.58

The default value of this bit is determined by the logical OR of the Auto-Negotiation strap

(autoneg_strap_x) and the negated speed strap (speed_strap_x). Table 13.9 defines the

default behavior of this bit. 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.

Refer to Section 4.2.4, "Configuration Straps," on page 45 for configuration strap

definitions.
