Oscillator range
PLL activation
When the resonator oscillator type is selected, these option bits select
the resonator oscillator current source corresponding to the frequency
range of the used resonator. When the external clock source is
selected, these bits are set to medium power (2 ~ 4 MHz)
000: Typ. frequency range (LP) = 1 ~ 2 MHz
001: Typ. frequency range (MP) = 2 ~ 4 MHz
010: Typ. frequency range (MS) = 4 ~ 8 MHz
011: Typ. frequency range (HS) = 8 ~ 16 MHz
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 4 MHz.
0: PLL x2 enabled
1: PLL x2 disabled
Caution: The PLL can be enabled only if the “OSCRANGE” (OPT3:1)
bits are configured to “MP - 2~4 MHz”. Otherwise, the device
functionality is not guaranteed.
