Data Bit
Description
Default
Value
0x03
TEMP MASK
15
TEMP mask bit.
0x0000
0 = temperature measurement is allowed to cause interrupt.
1 = temperature measurement is not allowed to cause interrupt.
AUX/VBAT MASK
14
AUX/VBAT mask bit.
0 = AUX/VBAT measurement is allowed to cause interrupt.
1 = AUX/VBAT measurement is not allowed to cause interrupt.
INT MODE
13
DAV/INT mode select.
0 = enable DAV mode.
1 = enable INT mode.
Note that this bit overrides any mask bits associated with individual channels.
GPIO ALERT
12
GPIO interrupt enable.
0 = GPIO can cause an alert on the INT output.
1 = mask GPIO from causing an alert on the INT output.
AUX/VBAT LOW
11
1 = AUX/VBAT below low limit.
AUX/VBAT HIGH
10
1 = AUX/VBAT above high limit.
TEMP LOW
9
1 = TEMP below low limit.
TEMP HIGH
8
1 = TEMP above high limit.
X+
7
1 = include measurement of Y position (X+ input).
Y+
6
1 = include measurement of X position (Y+ input).
Z1
5
1 = include Z1 touch-pressure measurement (X+ input).
Z2
4
1 = include measurement of Z2 touch-pressure measurement (Y input).
AUX
3
1 = include measurement of AUX channel.1
VBAT
2
1 = include measurement of battery monitor (VBAT).1
TEMP
1
1 = include temperature measurement.
Not used
0
Unused.
1
If GPIO is enabled in Control Register 2 (Bit 13), AUX and VBAT are both ignored. If AUX and VBAT are both selected and GPIO is disabled, AUX is ignored and VBAT is
measured.
