MSP430I2041TRHB JTAG fuse programming issue.

Hi, 

We are the off-line programmer manufacture and we are working on the MSP430I2041TRHB device support recently.

We can read/write the device successfully now, but there is a JTAG fuse program issue and also tried to programming by TI FET430UIF tools but get the fail to "Blow Fuse". 

The document mentions the i20xx device "physical fuse has been replaced by a programmed JTAG fuse"
We assumed this JTAG fuse might be reprogrammed and the programming procedure might be different as the others. 

Please advise is there document to specify the i20xx JTAG fuse programming?

Thanks for your time and support.
