12<P>When developing TWL or NITRO applications using the TWL-SDK, always call <CODE><A href="OS_Init.html" target="_self">OS_Init</A></CODE> as soon as <CODE>NitroMain</CODE> is entered. The functions called internally by <CODE>OS_Init</CODE> are required for proper behavior and cannot be called in any other order.<BR> (In the sample demo <CODE>os/cplusplus-1</CODE>, implemented in C++, the <CODE>OS_Init</CODE> function is called before <CODE>NitroMain</CODE> because memory management needs to be initialized.)
13</P>

15<P>The functions called inside <CODE>OS_Init</CODE> differ depending on whether the system is operating in NITRO or TWL mode. For details, see the <CODE><A href="OS_Init.html">OS_Init</A></CODE> function.
