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.

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. 

Debouncing period = 2

PENDBC

 ADCClock periods.
