The manual says that if p0.14 is low while reset is low, forces on-chip boot-loader to take over control of the part after reset. However, when I connect this pin to ground, while the user code is executing (Blinky), the program stops! When I connect it to the 3.3V pin on the motherboard, Blinky starts running again! And all this time reset is never low. Is this supposed to happen? It doesn't seem so according to the flowchart in the manual.
I'll describe what I did in detail:
1. Blinky is running 2. I connect p0.14 to ground 3. I reset, and the program stops 4. Now I connect p0.14 to a 3.3V pin, and Blinky starts running again, without having pressed reset 5. From now on I can start or stop the program by connecting p0.14 to 3.3V or ground, without using reset
What's happening?
PS - I am a beginner
