Chapter 3. LAN9252 EEPROM Programming
3.1
PROGRAMMING THE LAN9252 EEPROM
The LAN9252 configures itself to the desired mode (SPI, 6 HBI modes) by reading the
strap settings located in EEPROM. The LAN9252 EEPROM is programmed and vali-
dated via the TwinCAT master tool. The programming procedure is as follows:
Note 1:
This example utilizes the TwinCAT tool. Procedures may differ when using
other EtherCAT® master tools.
2:
Ensure the system network properties are configured properly for the Eth-
erCAT® frames, Ethernet cable linking your system, and EtherCAT® slave
board.
1. Load the corresponding ESI file in the directory path “C:\TwinCAT\Io\EtherCAT”.
For this demo, the ESI file for the 16-Bit Multiplexed Single-Phase Mode is used.
2. If TwinCAT installed successfully, a TwinCAT icon will be shown in the bot-
tom-right corner of the desktop. After clicking the icon, a pop-up list will display.
Select “System Manager”, as shown in Figure 3-1.
