STRAP NAME
Hard-Straps
Hard-straps are latched upon Power-On Reset (POR) or pin reset (nRST) only. Unlike soft-straps,
hard-straps always have an associated pin and cannot be overridden by the EEPROM Loader. These
straps are used as either direct configuration values or as register defaults.
all hard-straps and their associated pin. These straps, along with their pin assignments are also fully
defined in
Table 4.2 Soft-Strap Configuration Strap Definitions (continued)
Chapter 3, "Pin Description and Configuration," on page
Table 4.3 Hard-Strap Configuration Strap Definitions
DESCRIPTION
Port 0(External MII) Full-Duplex Flow Control Enable
Strap: Configures the default of the TX_FC_MII and
RX_FC_MII bits in the
Control Register (MANUAL_FC_MII)
manual full-duplex flow control is selected. When
configured low, flow control is disabled on RX/TX. When
configured high, flow control is enabled on RX/TX.
Port 0(External MII) Manual Flow Control Enable Strap:
Configures the default value of the MANUAL_FC_MII bit in
the
(MANUAL_FC_MII). When configured low, flow control is
determined by Virtual Auto-Negotiation (if enabled). When
configured high, flow control is determined by TX_FC_MII
and RX_FC_MII bits in the
Flow Control Register
Note:
SQE Heartbeat Disable Strap: Configures the Signal
Quality Error (Heartbeat) test function by controlling the
default value of the SQEOFF (bit 0) of the
Special Control/Status Register
(VPHY_SPECIAL_CONTROL_STATUS). When configured
low, SQEOFF defaults to 0 and SQE test is enabled. When
configured high, SQEOFF defaults to 1 and SQE test is
disabled.
Serial Management Mode Strap: Configures the default
serial management mode.
00 = Unmanaged mode
01 = SMI Managed Mode
10 = I
11 = SPI Managed Mode
Refer to
additional information on the various modes of the
LAN9313/LAN9313i.
EEPROM Type Strap: Configures the EEPROM type.

In MAC mode, this strap is not used. In this mode,
the Virtual PHY is not applicable, and full-duplex
flow control must be controlled manually by the
host, based upon the external PHYs Auto-
negotiation results.
