Table 14-9. Oscillator Gain Settings
GAIN[1:0] Function
0 Oscillator is used with gain G0 (XIN from 0.45 MHz to 12.0 MHz)
1 Oscillator is used with gain G1 (XIN from 12.0 MHz to 16.0 MHz)
2
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)
3
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)
