+ * and not delivered to the core.
+ *
+ * To solve this, interrupts are turned off before reads occur to I/O space.

+ *  - turns interrupts off every read (higher overhead, but lower latency)
+ *  - turns interrupts off every loop (low overhead, but longer latency)
+ *  - DMA version, which do not suffer from this issue. DMA versions have
+ *      different name (prefixed by dma_ ), and are located in
