The interrupt enable mask register is used to enable the interruption from a particular
interrupt source to the host.
Interrupt Enable Mask (where x = 3 to 0)
IE0: Default value is 0.
IE1: Keypad controller interrupt mask
IE2: Keypad controller FIFO overflow interrupt mask
IE3: GPIO controller interrupt mask
IE4: Combination key interrupt enable
Writing a ‘1’ to the IE[x] bit enables the interruption to the host.
