-\title{MBCI: Mini Bus Controller Interface Specification}
-\author{Amlal El Mahrouss}
-\date{2025}

-\begin{document}

-\maketitle
-
-\section{Overview}
-The Mini Bus Controller Interface (MBCI) is a standardized memory-mapped I/O bus specification designed for use in embedded systems and operating system kernels. It provides an extensible framework for managing hardware devices via a shared bus using memory-mapped registers. It is designed to remain abstract and platform-agnostic, leaving platform-specific interrupt and address logic to the HAL.
-
-\section{Signal Lines}
-The MBCI bus interface includes the following signal lines:
-
-\begin{itemize}
-  \item \textbf{VCC} (IN) – Power supply (OUT for MCU)
-  \item \textbf{CLK} (IN) – Clock line (OUT for MCU)
-  \item \textbf{ACK} (BI) – Acknowledge line containing packet frame
-  \item \textbf{D0-, D1-} (IN) – Host interface packet input
-  \item \textbf{D0+, D1+} (OUT) – Host interface packet output
-  \item \textbf{GND} (IN) – Ground line (OUT for MCU)
-\end{itemize}

-\section{Functions}
-
-\subsection*{MMIO Test}
-Tests if MMIO is accessible by writing and checking a challenge value. Times out if the bus does not respond.
-
-\begin{lstlisting}[language=C++,basicstyle=\ttfamily\footnotesize]
-inline BOOL busi_test_mmio(struct IMBCIHost* host, const UInt32 test);
-\end{lstlisting}
-
-\subsection*{Auth Key Reader}
-Reads the 24-bit auth key encoded in the last three bytes of the Extended Signature Block after verifying MMIO test success:
-
-\begin{lstlisting}[language=C++,basicstyle=\ttfamily\footnotesize]
-inline MBCIAuthKeyType mbci_read_auth_key(struct IMBCIHost* host);
-\end{lstlisting}
