[quote user="Luong Liu"]But I want use TUSB3410 to made BSL function for msp430, can you help me?[/quote]
If you go to the product page for that chip, you will see that there is an eval module for it. You can look at the technical data for that (schematics/BOM/CAD) and use as a starting point.
From there there are examples of how to connect to the BSL on the MSP430 devices. Easy enough to use the search feature.
