6 Channel Capacitive Touch Sensor with 6 LED Drivers
Datasheet
Bit 2 - CS3_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS3
(associated with the CS3 status bit).
Bit 1 - CS2_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS2
(associated with the CS2 status bit).
Bit 0 - CS1_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS1
(associated with the CS1 status bit).

The Repeat Rate Enable register determines the interrupt behavior of the buttons as described in
Section 4.6.1.
Bit 5 - CS6_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 6.
‘0’ - The repeat rate for CS6 is disabled. It will only generate an interrupt when a touch is detected
and when a release is detected no matter how long the touch is held for.
‘1’ (default) - The repeat rate for CS6 is enabled. In the case of a “touch” event, it will generate an
interrupt when a touch is detected and a release is detected. In the case of a “press and hold”
event, it will generate an interrupt when a touch is detected and at the repeat rate so long as the
touch is held. It will not generate an interrupt when a release is detected.
Bit 4 - CS5_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 5.
Bit 3 - CS4_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 4.
Bit 2 - CS3_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 3.
Bit 1 - CS2_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 2.
Bit 0 - CS1_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 1.

The Multiple Touch Configuration register controls the settings for the multiple touch detection circuitry.
These settings determine the number of simultaneous buttons that may be pressed before action is
taken.
Bit 7 - MULT_BLK_EN - Enables the multiple button blocking circuitry.
‘0’ - The multiple touch circuitry is disabled. The device will not block multiple touches.
‘1’ (default)- The multiple touch circuitry is enabled. The device will accept the number of touches
equal to programmed multiple touch threshold and block all others. It will remember which sensor
is valid and block all others until that sensor has been released.
