Table 27. Address 0x1A, CONFIG Field Descriptions (continued)
Bit Field Type Reset Description
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.

Bit Field Type Reset Description
15 AUTOSCAN_EN R/W 0 Auto-Scan Mode Enable
b0: Continuous conversion on the single channel selected by
CONFIG.ACTIVE_CHAN register field.
b1: Auto-Scan conversions as selected by
