6.5.4.3 External Reset
A debugger can pull the external RESET pin low to reset the device. The application software can reconfigure the RESET pin to the General Purpose Input/Output (GPIO) function, in which case the Reset function is lost. This reconfiguration is performed by the application code, i.e., after the Boot ROM has completed, so Interactive or Park modes can be entered to prevent such RESET pin reconfiguration.
