[15:9] INT_EN_MASK_MSB

[8] IE[x]:

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.
