CONFIG_ENTROPY_NRF5_ISR_THRESHOLD

ISR-mode random number pool low-water threshold

Type: int

Help

Low water-mark threshold in bytes to trigger entropy generation for ISR consumers. As soon as the number of available bytes in the buffer goes below this number hardware entropy generation will be started.
