Table 28-1.
In order to use the CAT module, other parts of the system must be configured correctly, as
described below.
The CAT pins may be multiplexed with other peripherals. The user must first program the I/O
Controller to give control of the pins to the CAT module. In QMatrix mode, the Y lines must be
driven by the CAT and analog comparators sense the voltage on the Y lines. Thus, the CAT (not
the Analog Comparator Interface) must be the selected function for the Y lines in the I/O
Controller.
By writing ones and zeros to bits in the Pin Mode Registers (PINMODEx), most of the CAT pins
can be individually selected to implement the QTouch method or the QMatrix method. Each pin
has a different name and function depending on whether it is implementing the QTouch method
or the QMatrix method. The following table shows the pin names for each method and the bits in
the PINMODEx registers which control the selection of the QTouch or QMatrix method.
