(gpio access, so jtaglib is in use)

Unfortunately I don't have suitable hardware to test this here. If you
want to experiment with the JTAG implementation, I'm happy to answer any
questions you might have.

can we debug it somehow? I don't find any doc about register reading.
I think the instruction is not executed. I modified 0x1fe to 0x200 and memory contents at address 0x200 is still unmodified.

I'm happy to answer questions, but unfortunately I don't have a lot of
time to dive in with debugging right now.
If you want to understand how the JTAG interface works, probably the
best thing to read first is the MSP430 Memory Programming User Guide.
