.. title:: ENTROPY_STM32_ISR_POOL_SIZE

.. option:: CONFIG_ENTROPY_STM32_ISR_POOL_SIZE

*ISR-mode random number pool size*

Type: ``int``

Help
====

Buffer length in bytes used to store entropy bytes generated by the
hardware to make them ready for ISR consumers.
Please note, that size of the pool must be a power of 2.
