You may be happy, I'm rather dismayed that this works.  It means that P0.14 
cannot be used in an application since it implies that if you get a for 
instance watchdog reset while P0.14 happens to be low rather than 
restarting the application you will enter ISP mode.  Dangerous, Dangerous....

The other processors I've used that use this required that an external 
reset be used before entering any special modes (such as ISP) in order to 
prevent such behaviour.  You did have to be careful about the reset state 
but that's something you needed to be careful of anyway.
