• PENDET: Pen Contact Detection Enable
0: Pen contact detection disable.
1: Pen contact detection enable.
When PENDET = 1, XPOS, YPOS, Z1, Z2 values of ADC_XPOSR, ADC_YPOSR, ADC_PRESSR registers are automatically
cleared when PENS = 0 in ADC_ISR.
• NOTSDMA: No TouchScreen DMA
0: XPOS, YPOS, Z1, Z2 are transmitted in ADC_LCDR.
1: XPOS, YPOS, Z1, Z2 are never transmitted in ADC_LCDR, therefore the buffer does not contains touchscreen values.
• PENDBC: Pen Detect Debouncing Period
Debouncing period = 2
PENDBC
ADCClock periods.
