Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Controls whether an interrupt on Port A can create an interrupt for the interrupt controller by not masking it. By default, all interrupts bits are unmasked. Whenever a 1 is written to a bit in this register, it masks the interrupt generation capability for this signal; otherwise interrupts are allowed through. The unmasked status can be read as well as the resultant status after masking. 0 Interrupt bits are unmasked (default) 1 Mask interrupt
