The interrupt enable mask register is used to enable the interruption from a particular
interrupt source to the host.
Interrupt Enable Mask (where x = 8 to 0)
IE0: Wake-up interrupt mask
IE1: Keypad controller interrupt mask
IE2: Keypad controller FIFO overflow interrupt mask
IE3: Reserved
IE4: Basic PWM controller 0 interrupt mask
IE5: Basic PWM controller 1 interrupt mask
IE6: Basic PWM controller 2 interrupt mask
IE7: Basic PWM controller 3 interrupt mask
IE8: GPIO controller interrupt mask
Writing a ‘1’ to the IE[x] bit enables the interruption to the host.
