I 2 C Bus Devices
There are two I 2 C EEPROM devices on the SPT711XPFCE. One connects only to the VIA Ethernet
switch, and the other connects to all four MSC711x devices. The I 2 C address for the EEPROM connected
to the switch is 0b1010001x. The I 2 C address for the EEPROM connected to MSC711x devices is
0b1010000x. The EEPROM devices are part number M24256-BWMN6G from ST Microelectronics. For
more information, refer to the manufacturer website ( http://www.st.com ).
0b1010000x, read the test pattern back, and then erase the EEPROM. To use this code to test the I 2 C
interface, simply write the test pattern using one of the four MSC711x devices and then read the test pattern
back from all four devices. Finally, use one of the four devices to erase the test pattern.
Example 2. I 2 C EEPROM Access Example Code for MSC711x Devices
#define I2C_BUF_SIZE 1024
unsigned char I2C_BUFFER[I2C_BUF_SIZE];
