| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 15:14 | ACTIVE_CHAN | R/W | 00 | Active Channel Selection
Selects channel for continuous conversions when MUX_CONFIG.AUTOSCAN_EN is 0. b00: Perform continuous conversions on Channel 0 b01: Perform continuous conversions on Channel 1 b10: Perform continuous conversions on Channel 2 (LDC1314 only) b11: Perform continuous conversions on Channel 3 (LDC1314 only) |
| 13 | SLEEP_MODE_EN | R/W | 1 | Sleep Mode Enable
Enter or exit low power Sleep Mode. b0: Device is active. b1: Device is in Sleep Mode. |
| 12 | RP_OVERRIDE_EN | R/W | 0 | Sensor RP Override Enable
Provides control over Sensor current drive used during the conversion time for Ch. x, based on the programmed value in the IDRIVEx field. Refer to Automatic IDRIVE Setting with RP_OVERRIDE_EN for details. b0: Override off b1: RP Override on |
| 11 | SENSOR_ACTIVATE_SEL | R/W | 1 | Sensor Activation Mode Selection
Set the mode for sensor initialization. Refer to Sensor Activation for details. b0: Full Current Activation Mode – the LDC will drive maximum sensor current for a shorter sensor activation time. b1: Low Power Activation Mode – the LDC uses the value programmed in DRIVE_CURRENTx during sensor activation to minimize power consumption. |
| 10 | AUTO_AMP_DIS | R/W | 0 | Automatic Sensor Amplitude Correction Disable
Setting this bit will disable the automatic Amplitude correction algorithm and stop the updating of the INIT_IDRIVEx field. b0: Automatic Amplitude correction enabled. b1: Automatic Amplitude correction is disabled. Recommended for precision applications. |
| 9 | REF_CLK_SRC | R/W | 0 | Select Reference Frequency Source
b0: Use Internal oscillator as reference frequency. b1: Reference frequency is provided from CLKIN pin. |
| 8 | RESERVED | R/W | 0 | Reserved. Set to b0. |
| 7 | INTB_DIS | R/W | 0 | INTB Disable
b0: INTB pin will be asserted when status register updates. b1: INTB pin will not be asserted when status register updates. If this mode is selected, the INTB pin level will be high. |
| 6 | HIGH_CURRENT_DRV | R/W | 0 | High Current Sensor Drive
b0: The LDC will drive all channels with normal sensor current (1.5mA max). b1: The LDC will drive channel 0 with current >1.5mA. This mode is not supported if AUTOSCAN_EN = b1 (multi-channel mode). |
| 5:0 | RESERVED | R/W | 00 0001 | Reserved. Set to b00’0001. |
