*Minimum threshold for external RAM allocation*

*Minimum threshold for external RAM allocation*

Type: ``int``

Help

.. code-block:: none

    Threshold to decide if memory will be allocated from DRAM
    or SPIRAM. If value of allocation size is less than this value,
    memory will be allocated from internal RAM.
