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 = Rotator Controller Interrupt Mask
IE4 = Rotator Controller Buffer Overflow Interrupt Mask
IE5 = PWM Channel 0 Interrupt Mask
IE6 = PWM Channel 1 Interrupt Mask
IE7 = PWM Channel 2 Interrupt Mask
IE8 = GPIO Controller Interrupt Mask
Writing a ‘1’ to the IE[x] bit will enable the interruption to the host.
