For the case of Autonomous QTouch, only the TOUCH_STATE_NULL and TOUCH_STATE_INIT
states apply in the State diagram.

?
The touch_at_sensor_init event causes a transition from TOUCH_STATE_NULL to
TOUCH_STATE_INIT.
The touch_deinit event causes a transition from TOUCH_STATE_INIT to
TOUCH_STATE_NULL.

QMatrix method pin selection for UC3L
Please refer AT32UC3L datasheet Table 28-2 Pin Selection Guide and Table 3-1 GPIO
Controller Function multiplexing, for mapping between the QMatrix method pin name and the
GPIO pin. It is possible to configure a maximum of 17 X Lines and 8 Y-Yk pairs. The X Line X8
(PA16) cannot be used for the QMatrix method as it is required to use this pin for the ACREFN
function.
The CAT module provides an option to enable a nominal output resistance of 1kOhm on specific
CAT module pins during the burst phase. The Table below captures the different QMatrix method
pin wherein a Resistive Drive can be optionally enabled. The rows marked with Grey indicate
that Resistive Drive option is not available on that pin. By carefully choosing the QMatrix method
