X and Yk pins wherein Resistive Drive can be enabled, saving on external components is
possible.
Section 6.3.1.1
QMatrix method sensor. The hardware arrangement for Wheel or Slider must be such that all
Touch channels corresponding to the Wheel or Slider belong to the same Yk Line.
Also,
can be used to specify a user defined configuration.
(The rows marked with Grey indicate that Resistive Drive option is not available on that pin)
6.3.7.2
6.3.7.2.1
The CAT module provides an internal discharge arrangement for QMatrix method. When this
arrangement is used along with the Resistive drive capability, minimal external component is
required as shown in the case A of Figure 27. When the Resistive drive is option is not enabled,
it is recommended to use 1kOhm resistors on X and Yk Lines external to the UC3L device. This
hardware arrangement is shown in case B.
