Bits 27:16 – XSCALE[11:0] Scale of XPOS
Indicates the max value that XPOS can reach. This value should be close to 212.
Bits 11:0 – XPOS[11:0] X Position
The position measured is stored here. If XPOS = 0 or XPOS = XSIZE, the pen is on the border.
When pen detection is enabled (ADC_TSMR.PENDET set to ‘1’), XPOS is tied to 0 while there is no detection of contact on the touchscreen (i.e., when the ADC_ISR.PENS bit is cleared).
