9.2.10.1 User Power Toggle Design Considerations

When using the debugger, if the power toggle rise time on Target Vdd is too slow (greater than 10 seconds) the User Power Toggle feature won't work. As an example, for the STK600 using the power switch gives you a too slow rise time but using the VTARGET jumper gives you a fast enough rise time.

For developers creating their own boards, ensure the Vdd rise time is less than 10 seconds.
