Note
    +
  • Unlimited means that the RTX kernel does not impose any limitations on the number. However, the available system memory resources limit the number of items you can create.
    • +
  • RAM requirements depend on the number of concurrently running threads.
    • +
  • The code and RAM size is calculated for ARMCC Compiler when using the MicroLib runtime library.
