Function
Oscillator is used with gain G0 (XIN from 0.45 MHz to 12.0 MHz)
Oscillator is used with gain G1 (XIN from 12.0 MHz to 16.0 MHz)
Oscillator is used with gain G2 (XIN equals 16.0 MHz. Used for e.g. increasing S/N
ratio, better drive strength for high ESR crystals)
Oscillator is used with gain G3 (XIN equals 16.0 MHz. Used for e.g. increasing S/N
ratio, better drive strength for high ESR crystals)
