/**@brief Flash Write
*
* Commands to write a buffer to flash
*
* This call initiates the flash access command, and its completion will be communicated to the
* application with exactly one of the following events:
* - NRF_EVT_FLASH_OPERATION_SUCCESS - The command was successfully completed.
* - NRF_EVT_FLASH_OPERATION_ERROR - The command could not be started.
*
* @note
* - This call takes control over the radio and the CPU during flash erase and write to make sure that
* they will not interfere with the flash access. This means that all interrupts will be blocked
* for a predictable time (depending on the NVMC specification in nRF51 Series Reference Manual
* and the command parameters).
*
*
* @param[in] p_dst Pointer to start of flash location to be written.
* @param[in] p_src Pointer to buffer with data to be written
* @param[in] size Number of 32-bit words to write. Maximum size is 256 32bit words.
*
* @retval ::NRF_ERROR_INVALID_ADDR Tried to write to a non existing flash address, or p_dst or p_src was unaligned.
* @retval ::NRF_ERROR_BUSY The previous command has not yet completed.
* @retval ::NRF_ERROR_INVALID_LENGTH Size was 0, or more than 256 words.
* @retval ::NRF_ERROR_FORBIDDEN Tried to write to or read from protected location.
* @retval ::NRF_SUCCESS The command was accepted.
