Note:
Table 146. Option byte 1 bit description (continued)
Table 147. Package selection (OPT7)
On the chip, each I/O port has up to eight pads. Pads that are not bonded to external pins
are in input pull-up configuration after reset. The configuration of these pads must be kept at
reset state to avoid added current consumption.

Caution: The PLL can be enabled only if the OSCRANGE (OPT3:1) bits
are configured to 2 ~ 4 MHz. Otherwise, the device functionality is not
guaranteed.
When the resonator oscillator type is selected, these option bits select
the resonator oscillator current source corresponding to the frequency
range of the resonator used. When the external clock source is
selected, these bits are set to medium power (2 ~ 4 MHz).
000: Typ. frequency range = 1 ~ 2 MHz
001: Typ. frequency range = 2 ~ 4 MHz
010: Typ. frequency range = 4 ~ 8 MHz
011: Typ. frequency range = 8 ~ 16 MHz
This option bit activates the PLL which allows multiplication by two of
the main input clock frequency. The PLL is guaranteed only with an
input frequency between 2 and 4 MHz. For this reason the PLL must
not be used with the internal RC oscillator.
