Multiple Channel Capacitive Touch Sensor and LED Driver
Datasheet
Bits 1-0 - CS9_LD_TH[1:0] - Controls the lid closure threshold for Capacitive Touch Sensor 9 (one of
the grouped sensors).
5.30.4
Lid Closure Threshold 4 Register
The Lid Closure Threshold 4 register controls the lid closure threshold for Capacitive Touch Sensors
13 - 14.
Bits 3-2 - CS14_LD_TH[1:0] - Controls the lid closure threshold for Capacitive Touch Sensor 14 (one
of the grouped sensors).
Bits 1-0 - CS13_LD_TH[1:0] - Controls the lid closure threshold for Capacitive Touch Sensor 13 (one
of the grouped sensors).

The Slider Velocity Configuration Register also controls the speed sensitive behaviors of the slider,
allowing the number of interrupts to be increased as the slide speed increases
Bit 7 - ACC_INT_EN - Enables the device to generate extra interrupts after an accelerated slide has
been detected.
‘0’ - The device will not generate extra interrupts during or after the slide has been detected.
‘1’ (default) - The device will generate extra interrupts after an accelerated slide is detected. The
number of extra interrupts generated will be proportional to the speed of the accelerated slide but
will not exceed the maximum number of extra interrupts as determined by the MAX_INT bits.
Bits 6-4 - MAX_INT[2:0] - (default 100b) Determine the maximum number of extra interrupts that will
be generated after a single slide (regardless of length). The variable “T” is the actual slide time and
the parameter SLIDE_TIME is set by bits [3:2] of this register.
