Group Configuration Register 1
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 4.5.2). The resolution is 35ms the range is from
35ms to 560ms as shown in Table 5.22.
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, then a Press and Hold event is detected. This has
no affect on whether a slide is detected within the group. If a slide is detected before or after the press
has been confirmed, it is treated as a separate event.
This is the maximum amount of time that a sensor in the Group can detect a button press to
differentiate between a tap and a press and hold. If a sensor detects a touch for less than or equal to
the M_PRESS[3:0] settings then, a Tap event is detected.
The resolution is 35ms the range is from 35ms to 560ms as shown in Table 5.22.
