RNG Firmware driver API description

38.2.1

How to use this driver

The RNG HAL driver can be used as follows:
1. Enable the RNG controller clock using __HAL_RCC_RNG_CLK_ENABLE() macro in
HAL_RNG_MspInit().
2. Activate the RNG peripheral using HAL_RNG_Init() function.
3. Wait until the 32 bit Random Number Generator contains a valid random data using
(polling/interrupt) mode.
4. Get the 32 bit random number using HAL_RNG_GenerateRandomNumber() function.
38.2.2

Initialization and de-initialization functions

This section provides functions allowing to:
Initialize the RNG according to the specified parameters in the RNG_InitTypeDef and
create the associated handle
DeInitialize the RNG peripheral
Initialize the RNG MSP
DeInitialize RNG MSP
This section contains the following APIs:
HAL_RNG_Init()
HAL_RNG_DeInit()
HAL_RNG_MspInit()
HAL_RNG_MspDeInit()
