+ * Notes on power-, reset- and nmi- button and control:
+ * - The -button signals can be used to monitor physical buttons.
+ * - The -control signals can be used to actuate the specific
+ *   operation.
+ * - In hardware, the -button signals are connected to the -control
+ *   signals through drivers with the -control signals being

+ *
+ * Notes on power-, reset- and nmi- button and control:
+ * - The -button signals can be used to monitor physical buttons.
+ * - The -control signals can be used to actuate the specific
+ *   operation.
+ * - In hardware, the -button signals are connected to the -control
+ *   signals through drivers with the -control signals being
