Multiple Channel Capacitive Touch Sensor and LED Driver

SMSC CAP1014
DATASHEET
‘0’ (default) - The Group Threshold register is updated independently of the Sensor 1 Threshold
register.
‘1’ - Writing the Sensor 1 Threshold register automatically overwrites the Group Threshold register
settings.
Bits 4-3 - ACAL_RT[1:0] - Determines the number of retries the digital logic will perform on the analog
calibration routine before it accepts the previous setting.
Bits 2 - 0 - CAL_CFG[2:0] - Determines the update time and number of samples of the automatic re-
calibration routine. The settings applies to all sensors universally (though individual sensors and the
group can be configured to support re-calibration - see Section 5.18).
Note 5.1
Recalibration Samples refers to the number of samples that are measured and averaged
before the Base Count is updated.
Note 5.2
Update Time refers to the amount of time (in polling cycle periods) that elapses before the
Base Count is updated.
