DATASHEET
The Button Noise Threshold is proportional to the programmed threshold as shown in Table 5.37.
5.25.1
Button Noise Threshold 1 Register
The Button Noise Threshold 1 register controls the noise threshold for Capacitive Touch Sensors 1-4.
Bits 7-6 - CH4_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 4.
Bits 5-4 - CH3_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 3.
Bits 3-2 - CH2_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 2.
Bits 1-0 - CH1_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 1.
5.25.2
Button Noise Threshold 2 Register
The Button Noise Threshold 2 register controls the noise threshold for Capacitive Touch Sensors 5 -
7 and the Grouped sensors.
Bits 7-6 - GR_BN_TH[1:0] - Controls the noise threshold for all grouped Capacitive Touch Sensors.
Bits 5-4 - CH7_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 7.
Bits 3-2 - CH6_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 6.
Bits 1-0 - CH5_BN_TH[1:0] - Controls the noise threshold for Capacitive Touch Sensor 5.
5.26
Slider Velocity Configuration Register
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.
