    pub regs: RNG,
}

Represents a RNG peripheral.

Fields

regs: RNG

Implementations

impl Rng

pub fn new(regs: RNG) -> Self

Initialize a RNG peripheral, including configuration register writes, and enabling and resetting its RCC peripheral clock.

pub fn read(&mut self) -> i32

Load a random number from the data register

pub fn reading_ready(&mut self) -> bool

Return true if a reading is available.

pub fn enable_interrupt(&mut self)

Enable an interrupt. An interrupt isgenerated when a random number is ready or when an error occurs. Therefore at each interrupt, check that: No error occured (SEIS and CEIS bits should be set to 0 in the RNG_SR register. A random number is ready. The DRDY bit must be set to 1 in the RNG_SR register.
