M_PRESS[3:0]
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
(see Section 4.8.2, "Capacitive Sensor 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 5.15.
