OPT5:4 = OSCTYPE[1:0] Oscillator Type

These option bits select the ST7 main clock source type.

OPT3:2 = OSCRANGE[1:0] Oscillator range

If the resonator oscillator type is selected, these option bits select the resonator oscillator.

This selection corresponds to the frequency range of the resonator used. If external source

is selected with the OSCTYPE option, then the OSCRANGE option must be selected with

the corresponding range.
