This register gives information of any button that is shorted to ground. If any bit in the register is set to '1', then the corresponding
button is connected to ground. CapSense buttons do not operate when they are connected to ground; these buttons are disabled.

This register gives information of any button that is shorted to another button. If any two buttons are shorted to each other, then bits
corresponding to both the buttons are set to '1' and the corresponding buttons are disabled.

This register gives information of buttons whose parasitic capacitance (C_P) is >40 pF. If any button C_P is >40 pF, then the bit in the
register is set and that button is disabled.
