	  This option enables releasing the Network 'force off' signal, which

	  as a consequence will power up the Network MCU during system boot.

	  Additionally, the option allocates GPIO pins that will be used by UARTE

	  of the Network MCU.

	  Note: GPIO pin allocation can only be configured by the secure Application

	  MCU firmware, so when this option is used with the non-secure version of

	  the board, the application needs to take into consideration, that the

	  secure firmware image must already have configured GPIO allocation for the

	  Network MCU.
