#define	Start_pll(clockfactor)   (PLLCSR = ( clockfactor | (1<<PLLE) ))
	Start the PLL at only 48 MHz, regarding CPU frequency Start the USB PLL with clockfactor clockfactor can be PLLx24, PLLx12, PLLx08 PLLx06, PLLx04, PLLx03.
#define	Is_pll_ready()   (PLLCSR & (1<<PLOCK) )
	return 1 when PLL locked
#define	Wait_pll_ready()   while (!(PLLCSR & (1<<PLOCK)))
	Test PLL lock bit and wait until lock is set.
#define	Stop_pll()   (PLLCSR &= (~(1<<PLLE)) )
	Stop the PLL.
#define	Pll_start_auto()   Start_pll(PLLx06)
	Start the PLL in autofactor mode regarding FOSC define.
