-\subsection{HAL abstraction layer}
-\label{sec-hal-abstraction-layer}
-Hardware Abstraction Layer (HAL) provides an abstraction over the real
-hardware. For example imagine an IO port with 8 pins. First four pins
-are connected directly to the GPIO pins on the MCU, another four pins
-are connected to an external integrated circuit, communicating with
-the MCU via SPI. This layer allows to control the IO pins
-independently of how that are connected to the MCU, providing a single
-unified API.
-
-Note that this functionality is not needed in the current version for
-\tgtBoardName, because all IOs are controlled directly by GPIO pins.
-
-As a result, the higher layers do not have to know anything about the
-wiring of the peripherals, they can just call read, write or configure
-function with a pin name as a parameter and the HAL handles all the
-details.
-
-The source files can be found in
-\texttt{$\langle$rpp\_lib$\rangle$/rpp/src/hal} and the header files can
-be found in \texttt{$\langle$rpp\_lib$\rangle$/rpp/include/hal} folder.

 \subsection{Drivers layer} 
 \label{sec-drivers-layer}
 The Drivers layer contains code for controlling the RPP peripherals.
