确实如此。http://processors.wiki.ti.com/index.php/JTAG_%28MSP430%29
However this JTAG interface is not 100% IEEE 1149.1 (JTAG) compatible. For example none of the MSP430 devices has Boundary Scan Cells. We only support the required command BYPASS, but don’t support the other required commands for example EXTEST and SAMPLE/PRELOAD.
Therefore there is no BSDL file for any MSP430 devices. In addition you can not put a MSP430 into a JTAG chain together with other devices.
