* @version V1.4.1
* @date 09-October-2015
* @brief RNG HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Random Number Generator (RNG) peripheral:
* + Initialization/de-initialization functions
* + Peripheral Control functions
* + Peripheral State functions
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
The RNG HAL driver can be used as follows:
(#) Enable the RNG controller clock using __HAL_RCC_RNG_CLK_ENABLE() macro
in HAL_RNG_MspInit().
(#) Activate the RNG peripheral using HAL_RNG_Init() function.
(#) Wait until the 32 bit Random Number Generator contains a valid
random data using (polling/interrupt) mode.
(#) Get the 32 bit random number using HAL_RNG_GenerateRandomNumber() function.
