When I applied 6.5V to pin 11 of the MSP430G2201 "Test" pin (TSSOP package) I expected to disable the Spy-bi-wire interface but I can download new code. I held the voltage to the pins for about 3 seconds. I took the board and applied the voltage from a bench power supply current limited to 500mA with the ground lead conneccted to pin 14 (Ground).
According to the datasheet once the fuse is blown the SBW is disabled.
Why can I still download code?
Since the flash is accessable is my code secure?
With the fuse blown can I still write to the flash?
Did I blow the fuse or do I need to apply a higher voltage?
