Power supply
The STMPE610 GPIO operates from a separate supply pin (V
provides a level-shifting feature to the STMPE610. The GPIO remains valid until V
removed.
The host system may choose to turn off V
not allowed to turn off supply to V
The touchscreen is always powered by V

GPIO rising edge detection enable register.
Setting this bit to ‘1’ would enable the detection of the rising edge transition.
The detection would be reflected in the GPIO edge detect status register.

Setting this bit to ‘1’ would enable the detection of the falling edge transition.
The detection would be reflected in the GPIO edge detect status register.

0x0F
Alternate function register. "‘0’ sets the corresponding pin to function as
touchscreen/ADC, and ‘1’ sets it into GPIO mode.
