Group Configuration Register 2
The Group Configuration 2 Register controls timings associated with the Capacitive Sensor channels
8 - 14 that are included in the group.
Bits 7 - 4 - MAX_DUR_G [3:0] - (default 1101b) - Determines the maximum time that a button is
allowed to be pressed until the Capacitive Touch sensor is recalibrated as shown in Table 6.22.
Bits 3 - 0 - RPT_RATE_SL[3:0] - (default 0100b) Determines the time duration between interrupt
assertions when auto repeat is enabled. This setting applies when a slide is detected on the Grouped
Sensors and acts as the base repeat rate that is adjusted based on the slide speed (see Section 5.5.5).
The resolution is 35ms the range is from 35ms to 560ms as shown in Table 6.23.
