Access:
• XPOS: 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 (PENDET set to ‘1’ in ADC_TSMR register), XPOS is tied to 0 while there is no detection of
contact on the touchscreen (i.e. when PENS bitfield is cleared in ADC_ISR register).
• XSCALE: Scale of XPOS
Indicates the max value that XPOS can reach. This value should be close to 2
