+function RPI_HardPWMSetClock(clock_divisor)
+// Function to set PWM clock. PWM clock frequency is 19.2MHz, which can be reduced 
+// using suitable clock_divisor (1 to 2048, powers of 2)
+//
+// Calling Sequence
+//	   RPI_HardPWMSetClock(clock_divisor) 
+//
+// Parameters
+//		clock_divisor: Value can be from 1 to 2048, powers of 2. 
+// Description
+//		This function decides pwm clock.  
+//		PWM frequency = (PWM Clock frequency/Clock divisor/range) 
+//				PWM clock frequency = 19.2 MHz
+//				clock divisor is setup using RPI_HardPWMSetClock
+//				range is setup using RPI_HardPWMSetRange 
+// Examples
