Group Configuration Register 1

The Group Configuration 1 Register controls timings associated with the Capacitive Sensor channels

8 - 14 that are included in the group.

Bits 7-4 - RPT_RATE_PH[3:0] - (default 0100b) Determines the time duration between interrupt

assertions when auto repeat is enabled. This setting applies when a press and hold condition is

detected on the on the Grouped Sensors (see Section 5.5). The resolution is 35ms the range is from

35ms to 560ms as shown in Table 6.23.

Bits 3- 0 - M_PRESS[3:0] - (default 0111b) - Determines the minimum amount of time that a sensor

in the Group must detect a button press to detect a Press and Hold event. If the sensor detects a

touch for longer than the M_PRESS[3:0] settings, a Press and Hold event is detected. This has no
