Bits 27:16 – YSCALE[11:0] Scale of YPOS
Indicates the max value that YPOS can reach. This value should be close to 212.
Bits 11:0 – YPOS[11:0] 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 (ADC_TSMR.PENDET set to ‘1’), YPOS is tied to 0 while there is no detection of contact on the touchscreen (i.e., when the ADC_ISR.PENS bit is cleared).
