Device/board initialization
This method is needed to initialize Arduino-shield type evaluation boards from NXP. This method takes one argument of "GPIO_base::ARDUINO_SHIELD" to set RESET and ADDRESS pins.
If the devoce is used as it self, this method doesn't need to be called.
env | This argument can be given as "GPIO_base::NONE" ot "GPIO_base::ARDUINO_SHIELD" |
