6.3.7.3
The clock for the CAT module, CLK_CAT, is generated by the Power Manager (PM). This clock is
turned on by default, and can be enabled and disabled in the PM. The user must ensure that
CLK_CAT is enabled before initializing the QTouch Library.
QMatrix operations also require the CAT generic clock, GCLK_CAT. This generic clock is
generated by the System Control Interface (SCIF), and is shared between the CAT and the
Analog Comparator Interface. The user must ensure that the GCLK_CAT is enabled in the SCIF
before using QMatrix functionality. For proper QMatrix operation, the frequency of GCLK_CAT
must be less than one fourth the frequency of CLK_CAT.
For QMatrix operation, the Analog comparators channels are used (using the ACIFB interface)
depending on the Y Lines enabled. See Note 4 in Section 6.3.7.4.
The QMatrix method acquisition using the CAT module requires two Peripheral DMA channels
that must be provided by the application.
6.3.7.4
The above figure represents a typical 4 X 4 matrix of QMatrix sensor arrangement along with the
channel numbers. The Channel numbering starts with Channel 0 (Ch0) and increase sequentially
from Ch0 to Ch15. Similarly the Sensor numbering starts with Sensor 0. The Channel number
signifies the order in which the QTouch Library stores the acquisition data in the memory.
Note: The touch_qm_sensor_config API must follow the above Channel and Sensor numbering
when configuring the Sensors.
6.3.7.5
For the QMatrix operation, the CAT_CLK and GCLK_CAT clocks must be setup appropriately as
a first step. The QMatrix and Common configuration parameters in the touch_config_at32uc3l.h
configuration must then be set up.
