Permit or prohibit P0[7:0] and P1[7:0] port interrupt.

0 (R/W): Interrupt prohibited (default)
Setting

IE[7:0] to 1 permits the corresponding interrupt, while setting to 0 blocks interrupts. Status
changes for the input pin with interrupt blocked do not affect interrupt occurrence.
To enable interrupt generation, the ITC P0 and P1 port interrupt enable bits must also be set to permit
interrupts.
