DATASHEET

Bits 3 - 2 - B_MULT_T[1:0] - Determines the number of simultaneous touches on all sensors before a

Multiple Touch Event is detected and sensors are blocked. The bit decode is given by Table 5.22.

Recalibration Configuration Register

The Recalibration Configuration register controls the automatic re-calibration routine settings as well

as advanced controls to program the Sensor Threshold register settings.

Bit 7 - BUT_LD_TH - Enables setting all Sensor Threshold registers by writing to the Sensor 1

Threshold register.

‘0’ - Each Sensor X Threshold register is updated individually.

‘1’ (default) - Writing the Sensor 1 Threshold register will automatically overwrite the Sensor

Threshold registers for all sensors (Sensor Threshold 1 through Sensor Threshold 6). The

individual Sensor X Threshold registers (Sensor 2 Threshold through Sensor 6 Threshold) can be

individually updated at any time.

Bits 4 - 3 - NEG_DELTA_CNT[1:0] - Determines the number of negative delta counts necessary to

trigger a digital re-calibration as shown in Table 5.24.
