Button Configuration Register
The Button Configuration Register controls timings associated with the Capacitive Sensor channels 1
- 7 that are not Grouped.
Bits 7 - 4 - MAX_DUR_B [3:0] - (default 1010b) - 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_B[3:0] - (default 0100b) Determines the time duration between interrupt
assertions when auto repeat is enabled. The resolution is 35ms the range is from 35ms to 560ms as
shown in Table 6.23.
