and it is measured by a 12-stage binary counter. Lock-up time is about 0.41ms at f
10MHz.
10MHz measured by 13-stage binary counter.
Clock doubler (PLL)
PLL0 outputs the f
Since Reset initializes PLL0 to stop status, so setting to PLLCR0 and PLLCR1-register is
As with an oscillator, this circuit requires time to stabilize. This is called the lock-up time
PLL (PLL1) which is special for USB is built in. Lock-up time is about 0.82ms at f
Table 3.3.2 shows the frequency of f
The input frequency range (High frequency oscillation) for PLL is as follows:
f
The logic of PLLCR0<LUPFG> is different from 900/L1’s DFM.
Exercise care in determining theend of lock-up time.
It is not possible to turn ON both PLL0 and PLL1 simultaneously.
If turning ON simultaneously, one PLL should be turn ON after finishing the lock up of the other PLL.
