    OSCRANGE of option byte is meaningful only when resonator is used?

    if 8MHz is used, then which setting is prefered? HS:8-16MHz or MS:4-8MHz?

    If 8MHz is used then you should go for MS:4-8MHz.

    OSCRANGE is necessary for two reasons:

    1. to select the suitable source about the oscillation circuitery when you are using a resonator

    2. to set the nominal frequency on other conditions.

    Concerning your question you can select HS:8-16MHz or MS:4-8MHz.

    Hi Luca,

    But isn't it true that since the oscillator driving current is less when you select the option MS:4-8MHz instead of HS:8-16MHz.

    In that case though you can use both it is preferable to use MS:4-8MHz.

    Thanks
