* nRF51 Random Number Generator

*
|
|
* QEMU interface:
|
|
* + Property "period_unfiltered_us": Time between two biased values in
|
|
* microseconds.
|
|
* + Property "period_filtered_us": Time between two unbiased values in
|
|
* microseconds.
|
|
* + sysbus MMIO regions 0: Memory Region with tasks, events and registers
|
|
* to be mapped to the peripherals instance address by the SOC.
|
|
* + Named GPIO output "irq": Interrupt line of the peripheral. Must be
|
|
* connected to the associated peripheral interrupt line of the NVIC.
|
|
* + Named GPIO output "eep_valrdy": Event set when new random value is ready
|
|
* to be read.
|
|
* + Named GPIO input "tep_start": Task that triggers start of continuous
|
|
* generation of random values.
|
|
* + Named GPIO input "tep_stop": Task that ends continuous generation of
|
|
* random values.
|
|
*
|
|
* Accuracy of the peripheral model:
|
|
* + Stochastic properties of different configurations of the random source
|
|
* are not modeled.
|
|
* + Generation of unfiltered and filtered random values take at least the
|
|
* average generation time stated in the production specification;
|
|
* non-deterministic generation times are not modeled.
