Problems with the I2C emulated EEPROM for TUSB3410 with CC430F5137

Other Parts Discussed in Thread: CC430F5137, TUSB3410

Hello,

I developed a new board that is based on the CC430F5137 and the TUSB3410. The board has 2 crystals:

1) 12MHz for the TUSB3410

2) 26MHz for the CC430F5137

I adapted the software I found to emulate the EEPROM with the miccrocontroler that is inside de SoC CC430F5137 (slaa276a). The CC430 UCS is configured as:

- ACLK: REFOCLK ~32768Hz

-SMCLK: DCOCLK ~1MHz

- MCLK: XT2CLK 26MHz

Once the CC430 is initialized and after the TUSB3410 is resumed from reset state. I am able to read the 0xA0 00 00 message from the I2C and after that another message that starts with 0xA1 (write bit) and then I write the signature OK. After that a noteher message starts with 0xA1 (write bit) and I write the following descriptor block: 0x03 12 00 33 (the one I found in the demo software), but after this nothin happens. 

I have checked all in the oscilloscope. What could be the problem? Any idea?

Thanks in advance.
