CAP1298

5.9

Sensor Input Configuration 2 Register

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

use auto repeat must detect a sensor pad touch to detect a “press and hold” event (see Section 4.9.2, "Capacitive Sen-

sor Input Interrupt Behavior"). If the sensor input detects a touch for longer than the M_PRESS[3:0] settings, a “press

and hold” event is detected. If a sensor input detects a touch for less than or equal to the M_PRESS[3:0] settings, a

touch event is detected.

The resolution is 35ms and the range is from 35ms to 560ms as shown in Table 5-17.
