6 Channel Capacitive Touch Sensor with 6 LED Drivers
Datasheet
The Sensor Enable registers determine whether a Capacitive Touch Sensor input is included in the
sampling cycle. The length of the sampling cycle is not affected by the number of sensors measured.
Bit 5 - CS6_EN - Enables the CS6 input to be included during the sampling cycle.
‘0’ - The CS6 input is not included in the sampling cycle.
‘1’ (default) - The CS6 input is included in the sampling cycle.
Bit 4 - CS5_EN - Enables the CS5 input to be included during the sampling cycle.
Bit 3 - CS4_EN - Enables the CS4 input to be included during the sampling cycle.
Bit 2 - CS3_EN - Enables the CS3 input to be included during the sampling cycle.
Bit 1 - CS2_EN - Enables the CS2 input to be included during the sampling cycle.
Bit 0 - CS1_EN - Enables the CS1 input to be included during the sampling cycle.

The Sensor Configuration Register controls timings associated with the Capacitive Sensor channels 1
- 6.
Bits 7 - 4 - MAX_DUR[3:0] - (default 1010b) - Determines the maximum time that a sensor is allowed
to be touched until the Capacitive Touch sensor is recalibrated as shown in Table 5.12.
