Revision 1.64 (01-15-09)
DATASHEET
Bits 1 - 0 - G_MULT_T[1:0] - Determines the number of simultaneous touches on all Grouped buttons
before a Multiple Touch Event is flagged. If the number of multiple buttons touches is greater than the
threshold value then a Multiple Touch Event is flagged. The bit decode is given by Table 5.31.
5.23
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 button 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 buttons (Sensor Threshold 1 through Sensor Threshold 7). The individual
Sensor X Threshold registers (Sensor 2 Threshold through Sensor 7 Threshold) can be individually
updated at any time.
Bit 6 - GP_LD_TH - Enables setting the Group Threshold register by writing to the Sensor 1 Threshold
register.
