M_PRESS[3:0]
Default
07h
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. 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 the range is from 35ms to 560ms as shown in Table 6-16.
