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

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

and QTouch GroupA/B
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.
