Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15:14 | ACTIVE_CHAN | R/W | 00 | Active channel selection Selects channel for continuous conversions when MUX_CONFIG.SEQUENTIAL is 0. b00: Perform continuous conversions on Channel 0 b01: Perform continuous conversions on Channel 1 b10: Perform continuous conversions on Channel 2 (FDC2114, FDC2214 only) b11: Perform continuous conversions on Channel 3 (FDC2114, FDC2214 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 | RESERVED | R/W | 0 | Reserved. Set to b1. |
11 | SENSOR_ACTIVATE_SEL | R/W | 1 | Sensor activation mode selection. Set the mode for sensor initialization. b0: Full current activation mode – the FDC drives the maximum sensor current for a shorter sensor activation time. b1: Low power activation mode – the FDC uses the value programmed in DRIVE_CURRENT_CHx during sensor activation to minimize power consumption. |
10 | RESERVED | R/W | 0 | Reserved. Set to b1. |
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: Asserts INTB pin when status register updates. b1: Does not assert INTB pin when status register updates |
6 | HIGH_CURRENT_DRV | R/W | 0 | High Current Sensor Drive b0: The FDC drives all channels with normal sensor current (1.5mA maximum). b1: The FDC drives 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 |
