MSP430 fuse blowing issue

Hello All,

I am using IAR Embedded Work bench C/C++ compiler for MSP 430 devices. I
would like to program the fuse of MSP430 chip using JTAG interface. I
studied from MSP 430 Embedded Workbench User guide, which directed me to
use the 'Secure' option in the Emulator menu after downloading the
Software using JTAG interface.



I downloaded the software using JTAG interface & found that the 'Secure'
option in the Emulator menu is not enabled. So I could not program the
fuse.



1)How can we enable the 'Secure' option?
2)How to program the fuse using JTAG interface?
3)How should I proceed?

Thanks in advance.
