Function

Oscillator range

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

OPT3:1 OSCRANGE[2:0] 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

Product(s) OPT0

PLL OFF

PLL activation

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.
