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.

IEGPIOR

Interrupt enable GPIO mask register

Address:

0x08, 0x09

Type:

Reset:

0x00

Description:

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.
