Figure 12. Panel Setup and Measurement Commands—MAX11800–MAX11803
combined command which includes an auxiliary mea-
surement. Register 0x0A specifies the configuration for
auxiliary measurements.
In CINT, the MAX11800–MAX11803 continue to monitor
for the touch status of the panel. The devices report any
change in touch status in real time during an auxiliary
measurement procedure.

When performing auxiliary measurements in edge
interrupt mode, the MAX11800–MAX11803 temporarily
suspend the panel touch monitoring. The devices noti-
fy the AP after the completion of the auxiliary measure-
ment when a new touch occurs during the auxiliary
measurement.
