Description

8:0

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 = 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.
