Detailed Description

These functions allow to control the PLL.

Defines
#define	Is_pll_ready()   (PLLCSR & (1<<PLLOCK) )
	Return 1 if the PLL is ready.
#define	Start_pll(frequency)   (PLLCSR = ( (((frequency>>6)&1)<<2) | (1<<1) ) )
	Start the PLL at the parameter frequency (only 64 or 32 MHz).
#define	Start_pll_32_mega()   (PLLCSR = 0x02)
	Start the PLL at 32MHz.
#define	Start_pll_64_mega()   (PLLCSR = 0x06)
	Start the PLL at 64MHz.
#define	Stop_pll()   (PLLCSR = 0x00)
	Stop the PLL.
#define	Wait_pll_ready()   while (!(PLLCSR & (1<<PLLOCK)))
