WebThe RNG peripheral is based on continuous analog noise that provides a random 32-bit value which will be explained in detail later on. The RNG is able to generate four 32-bit random numbers at a minimum frequency of 213 system clock cycles. Rule of thumb is the lower the RNG clock, the better the entropy for the sampled random source.

WebIf a number is available in the RNG_DR register, it must not be used because it may not have enough entropy. In this case, it is recommended to clear the SEIS bit using __HAL_RNG_CLEAR_IT(), then disable and enable the RNG peripheral to reinitialize and restart the RNG. RNG ErrorCallback() API is called once whether SEIS or CEIS are set. … WebReturn values: Frequency. in Hz. Definition at line 677 of file stm32l4xx_hal_rcc_ex.c.
