+ * @note 1
+ * This critical section is only used to fix such condition:
+ *
+ * define: lock_bits = (lock->status & LOCK_MASK) >> LOCK_SHIFT;  This `lock_bits` is the Bit 29-20 of the lock->status
+ *
+ * 1. spi_hdl_1:
+ *    acquire_end_core():
+ *    uint32_t status = lock_status_clear(lock, dev_handle->mask & LOCK_MASK);
+ *
+ *    Becuase this is the first `spi_hdl_1`, so after this , lock_bits == 0`b0. status == 0
+ *
+ * 2. spi_hdl_2:
+ *    acquire_core:
+ *    uint32_t status = lock_status_fetch_set(lock, dev_handle->mask & LOCK_MASK);
+ *
+ *    Then here status is 0`b0, but lock_bits == 0`b10. Because this is the `spi_hdl_2`
+ *
+ * 3. spi_hdl_2:
+ *    `acquire_core` return true, because status == 0. `spi_bus_lock_acquire_start(spi_hdl_2)` then won't block.
+ *
+ * 4. spi_hdl_2:
+ *    spi_device_polling_end(spi_hdl_2).
+ *
+ * 5. spi_hdl_1:
+ *    acquire_end_core:
+ *    status is 0, so it cleas the lock->acquiring_dev
+ *
+ * 6. spi_hdl_2:
+ *    spi_device_polling_end:
+ *    assert(handle == get_acquiring_dev(host)); Fail
+ *
+ * @note 2
+ * Only use this critical section in this condition. The critical section scope is limited to the smallest.
+ * As `spi_bus_lock` influences the all the SPIs (including MSPI) a lot!
