CONFIG_ENTROPY_CC13XX_CC26XX_SAMPLES_PER_CYCLE

Number of samples to generate entropy

Type: int

Help

The number of samples used to generate entropy. The time required to generate 64 bits of entropy is determined by the number of FROs enabled, the sampling (system) clock frequency, and this value.
