Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15 - 6 | RAMP_DLY_CNT | R/W | 111h | For ramping mode, RAMP_DLY_CNT and RAMP_SCALE_COUNT determine the minimum necessary time taken for VCO calibration during the ramp.
Min. VCOCal time = (1 / fsmc) / (RAMP_DLY_CNT × 2RAMP_SCALE_COUNT), where fsmc = fOSCin / 2CAL_CLK_DIV. |
5 | RAMP_MANUAL | R/W | 0h | Selects the ramping mode.
0: Automatic ramping mode 1: Manual (Pin) ramping mode |
4 | RAMP1_NEXT | R/W | 0h | Defines what ramp comes after RAMP1.
0: RAMP0 1: RAMP1 |
3 - 2 | R/W | 0h | Program 0h to this field. | |
1 - 0 | RAMP1_NEXT_TRIG | R/W | 0h | Defines what triggers the next ramp.
0: RAMP1_LEN timeout counter 1: Trigger A 2: Trigger B 3: Not used |
