PLL activation
Oscillator range
When the resonator oscillator is selected, these option bits select the resonator
oscillator current source corresponding to the frequency range of the used
resonator. Otherwise, these bits are used to select the normal frequency range.
000: Typ. frequency range (LP) = >1~2MHz
001: Typ. frequency range (MP) = >2~4MHz)
010: Typ. frequency range (MS) = >4~8MHz)
011: Typ. frequency range (HS) = >8~16MHz)
This option bit activates the PLL which allows multiplication by two of the main
input clock frequency. The PLL must not be used with the internal RC oscillator.
The PLL is guaranteed only with an input frequency between 2 and 4MHz.
0: PLL x2 enabled
1: PLL x2 disabled
Caution: The PLL can be enabled only if the ‘OSC RANGE’ (OPT3:1) bits are
configured to ‘MP - 2~4MHz’. Otherwise, the device functionality is not
guaranteed.
Caution 2: When the PLL is used with an external clock signal, the clock signal
must be available on the OSCIN pin before the reset signal is released.
