.. title:: ENTROPY_NRF5_ISR_THRESHOLD

.. option:: 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.

Direct dependencies
===================
