-      Radioberry clock
+      	Radioberry supporting clock
 	  
-	  This program sets the (fysical pin 36) gpio6 clock pin to 10 Mhz.
+	This program sets the (fysical pin 7) GPCLK0 pin to 10 Mhz.
+
+	This supporting clock is used for:
+		-) reset handler
+		-) iambic (cw keying) 
+		-) heartbeat
+		-) ad9866 spi controlling
+
+	It is an important clock but the timing is not used for
+	the ADC and DAC conversions.
+
+	This program must be called (clock must be set first) before loading the firmware.
