11.4.3. Register Map
The Intel-provided HAL device driver accesses the device registers directly. If you are writing a device driver and the HAL driver is active for the same device, your driver will conflict and fail to operate.
The UART Core Register map table below shows the register map for the UART core. Device drivers control and communicate with the core through the memory-mapped registers.
