Interrupt, power supply & reset

STMPE801 could be configured to generate an interrupt when there is a logic transition of

any of the GPIO configured as input.

8.1

Interrupt enable GPIO mask register (IEGPIOR)

IEGPIOR register is used to enable the interruption from a particular GPIO interrupt source

to the host. The IEG[7:0] bits are the interrupt enable mask bits correspond to the GPIO[7:0]

pins.
