The GPIO interrupt enable register is used to enable the interruption from a particular
GPIO interrupt source to the host. The IEg[7:0] bits and the interrupt enable mask bits
correspond to the GPIO[7:0} pins.
Interrupt enable GPIO mask (where x = 7 to 0)
Writing a ‘1’ to the IE[x] bit will enable the interruption to the host.
