The Touch Screen Pin Offset field is used to indicate which AD pins are connected to the resistive touch screen film edges. Only
an offset is specified and it is assumed that the touch screen films are connected sequentially from the specified offset pin and
up to and including offset + 3 (4 pins).
0: AD pins are not used to drive VDD in Touch Screen sequence.
1: AD pins are used to drive VDD in Touch Screen sequence.
Note: If the selected I/O voltage configuration is incompatible with the Analog-to-Digital converter cell voltage specification, this
bit must stay cleared to avoid damaging the ADC. In this case the DP pins must be used to drive VDD instead, as described in
Section
case the DP pins can be ignored.
0: The analog compare functionality is disabled.
1: The analog compare functionality is enabled.
0: The pen detect functionality is disabled.
1: The pen detect functionality is enabled.
0: Touch Screen Mode is disabled.
1: Touch Screen Mode is enabled.

26.7.3. If the I/O and ADC voltages are compatible, the AD pins can be used directly by writing a one to this bit. In this
