we are using the chip nRF51822 CEAAE00.
We want to use the pin 0 as output. It is configured as below 
 NRF_GPIO-&amp;gt;PIN_CNF[0] = (GPIO_PIN_CNF_SENSE_Disabled &amp;lt;&amp;lt; GPIO_PIN_CNF_SENSE_Pos)
 | (GPIO_PIN_CNF_DRIVE_S0S1 &amp;lt;&amp;lt; GPIO_PIN_CNF_DRIVE_Pos)

This pin driver can be high, when &amp;quot;ble_stack_init();&amp;quot; is not called.
