Access:
• YPOS: Y Position
The Position measured is stored here. if YPOS = 0 or YPOS = YSIZE, the pen is on the border.
When pen detection is enabled (PENDET set to ‘1’ in ADC_TSMR register), YPOS 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).
• YSCALE: Scale of YPOS
Indicates the max value that YPOS can reach. This value should be close to 2
