Interrupt system
The STMPE1600 can be configured to generate an interrupt when there is a logic transition
on any of the GPIO configured as an input.
[15:0] IEG[x]: Interrupt enable GPIO mask (where x = 15 to 0)

Interrupt enable GPIO mask register (IEGPIOR)
The IEGPIOR register is used to enable the interruption from a particular GPIO
interrupt source to the host. The IEG[15:0] bits are the interrupt enable mask bits
corresponding to the GPIO[15:0] pins.
Writing a ‘1’ to the IE[x] bit will enable the interruption to the host.
