EMULATING EEPROM I2C CONECTION TUSB3410

Other Parts Discussed in Thread: TUSB3410

Hello, I'm traing to emulate the EEPROM with a microcontroller MSP430F261X using a TUSB3410. I’m having troubles with the configuration of the i2c ports, and the order the header should be introduce in the microcontroller.

Regarding the Header order:

Step 1 - Create device signature, Step 2 - Create descriptor blocks, Step 3 - Define String Descriptors (string index 1=Manufacturer, string index 2=Product, string index 3=Serial #), Step 4 - Terminate the header.

I'm attaching a file that shows the proper order: TUSB3410_Serialized.txt

About the I2C commands, you can go to this link: http://focus.ti.com/lit/ds/symlink/tusb3410.pdf . Look for Chapter 10 (page 52), there are some registers that can control the stop condition for read and write operations, transmitter and receiver handshake signals with their respective interrupt enable bits, etc...

Best Regards,

Ismael
