SYNC_DCO_EN=value1, XTAL_SEL=value1
DCO1 Sync Control Register 1
| SYNC_PRELOAD | Counter target value, which defines the update cycle 8191 (value1): Longest integration time = best accuracy |
| SYNC_DCO_EN | DCO1 synchronization feature enable 0 (value1): No DCO1 synchronization via an external clock source. This option is used for the DCO1 calibration using the temperature sensor. 1 (value2): DCO1 gets synchronized via an external clock source. |
| XTAL_SEL | Oscillator Source select 0 (value1): OSC_LP is selected 1 (value2): OSC_HP is selected |
