+/*
+ * This will "factory reset" a wiiceiver chip by returning saved values
+ * to default, as present in a new / unflashed ATMega328P
+ * 
+ * This is NOT MAGIC -- it doesn't really do anything you can't easily
+ * do in a working wiiceiver, but it might help troubleshooting in 
+ * specific cases.
+ *
+ * To reset a wiiceiver the easy way:
+ * 1) start it and hold C; count to 10
+ * 2) hold down until the wheels stop, then all the way right for 5 secs
+ * 
+ * This will re-calibrate the nunchuck stick, and set auto-cruise to 0
+ *
+ * If for whatever reason you want to do the hard way:
+ * 1) upload this to your wiiceiver
+ * 2) observe both red & green LEDs lot solid
+ * 3) upload the wiiceiver code
+ * 4) observe wiiceiver acting like a "new" device, with
+ *    default settings for the joystick calibration and auto-cruise
