Description
TEMP mask bit.
0 = temperature measurement is allowed to cause interrupt.
1 = temperature measurement is not allowed to cause interrupt.
AUX/VBAT mask bit.
0 = AUX/VBAT measurement is allowed to cause interrupt.
1 = AUX/VBAT measurement is not allowed to cause interrupt.
DAV/INT mode select.
0 = enable DAV mode.
1 = enable INT mode.
This bit overrides any mask bits associated with individual channels.
GPIO interrupt enable.
0 = GPIO can cause an alert on the INT output.
1 = mask GPIO from causing an alert on the INT output.
1 = AUX/VBAT below low limit.
1 = AUX/VBAT above high limit.
1 = TEMP below low limit.
1 = TEMP above high limit.
1 = include measurement of Y position (X+ input).
1 = include measurement of X position (Y+ input).
1 = include Z1 touch-pressure measurement (X+ input).
1 = include measurement of Z2 touch-pressure measurement (Y− input).
1 = include measurement of AUX channel.1
1 = include measurement of battery monitor (VBAT).1
1 = include temperature measurement.
Unused.
Default Value
0x0000
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.
