Touch Screen Mode
If the PDC is enabled, all the converted data are transferred contiguously in the memory buffer.
The bit LOWRES defines which resolution is used, either 8-bit or 10-bit, and thus the width of the
PDC memory buffer.
Writing TSAMOD to “Touch Screen Only Mode” automatically enables the touch screen pins as
analog inputs, and thus disables the digital function of the corresponding pins.
In Touch Screen Mode, the channels 0 to 3 corresponding to the Touch Screen inputs are auto-
matically activated and the bits CH0 to CH3 are automatically set in the
Status
The remaining channels can be either enabled or disabled by the user and their conversions are
performed at the end of each touch screen sequence.
The resolution is forced to 10 bits, regardless of the LOWRES bit setting.
At each trigger, if the bit PRES in
is performed to measure only position.
The resulting buffer is 16 bits wide and its structure stored in memory is:

6. If Channel 2 is enabled, convert Channel 2 and store result in both TSADCC_CDR2
