[Mspgcc-users] [OT] JTAG IF - could this be activated incidentally?

[Hardy Griech]

Hi,

if the JTAG connector is removed during debugging (CPU halted), the CPU 
remains halted (that's the intention of the JTAG debugging IF).  No 
internal watchdog recovers the MSP430 from the state.

My concern is, if this state (JTAG debugging, CPU halted) could be 
generated by radiation or bit flips caused by other reasons.

If this would be the case, an external watchdog would be required 
always.  My hope is, that JTAG debugging is somehow checksum protected 
and thus likelihood of the above event would be (almost) zero.

Does anybody from the list has knowledge about the implementation 
details and has an answer?

Thanks!

Hardy
