3.1.1.2 SERIAL MANAGEMENT MODE CONFIGURATION
Serial Management Mode selection strap (MNGT0) is used to configure the default
value of the Serial Management Mode Strap hard-strap (serial_mngt_mode_strap)
through jumpers as shown below in Table 3-2.

3.1.1.3 EEPROM SIZE CONFIGURATION:
The EEPROM size configuration strap (J6 & J9) determines the supported EEPROM
size range. A low selects 1Kbits (128 x 8) through 16Kbits (2K x 8)_24C16. A high
selects 32Kbits (4K x 8) through 512Kbits (64K x 8) or 4Mbits (512K x 8)_24C512 as
shown below in Table 3-3.

3.1.1.4 ENERGY-EFFICIENT ETHERNET CONFIGURATION
EEE_EN configuration strap is used to configure the default value of the EEE Enable
2-1 soft-straps (EEE_enable_strap_[2:1]) through jumpers as shown below in
Table 3-4.
Note: “EEE_enable_strap_1” strap is used for the LAN9353 when in Port 1 inter-
nal PHY mode.
