- * @brief Checks if an ISR in progress.

- * and interrupt and false otherwise.   A return value of true indicates
- * that the caller is an interrupt service routine, NOT a thread.
- *
- * @retval true Returns true when called from an ISR.
- * @retval false Returns false when not called from an ISR.
