+ * <p>
+ * The ARMCM3 port allows some architecture-specific configurations settings
+ * that can be specified externally, as example on the compiler command line:
+ * <ul>
+ * <li>@p INT_REQUIRED_STACK, this value represent the amount of stack space used
+ * by an interrupt handler between the @p extctx and @p intctx
+ * structures.<br>
+ * In practice this value is the stack space used by the chSchDoReschedule()
+ * stack frame.<br>
+ * This value can be affected by a variety of external things like compiler
+ * version, compiler options, kernel settings (speed/size) and so on.<br>
+ * The default for this value is @p 0x10 which should be a safe value, you
+ * can trim this down by defining the macro externally. This would save
+ * some valuable RAM space for each thread present in the system.<br>
+ * The default value is set into <b>./ports/ARMCM3/chcore.h</b>.</li>
+ * <li>@p BASEPRI_USER, this is the @p BASEPRI value for the user threads. The
+ * default value is @p 0 (disabled).<br>
+ * Usually there is no need to change this value, please refer to the
+ * Cortex-M3 technical reference manual for a detailed description.</li>
+ * <li>@p BASEPRI_KERNEL, this is the @p BASEPRI value for the kernel lock code.
+ * The default value is 0x10.<br>
+ * Code running at higher priority levels must not invoke any OS API.<br>
+ * Usually there is no need to change this value, please refer to the
+ * Cortex-M3 technical reference manual for a detailed description.</li>
+ * <li>@p ENABLE_WFI_IDLE, if set to @p 1 enables the use of the @p wfi
+ * instruction from within the idle loop. This is defaulted to 0 because
+ * it can create problems with some debuggers. Setting this option to 1
+ * reduces the system power requirements.</li>
