TRNGCC26X0.h File Reference

Detailed Description

TRNG driver implementation for the CC26X0 family.

============================================================================

Warning

This is a beta API. It may change in future releases.

This file should only be included in the board file to fill the TRNG_config struct.

The CC26X0 family has a dedicated hardware TRNG based on sampling multiple free running oscillators. With all FROs enabled, the TRNG hardware generates 64 bits of entropy approximately every 5ms. The driver implementation chains multiple 64-bit entropy generation operations together to generate an arbitrary amount of entropy.

The driver implementation does not perform runtime checks for most input parameters. Only values that are likely to have a stochastic element to them are checked (such as whether a driver is already open). Higher input paramter validation coverage is achieved by turning on assertions when compiling the driver.
