Register 6: GPIO Interrupt Mask (GPIOIM), offset 0x410
The GPIOIM register is the interrupt mask register. Setting a bit in the GPIOIM register allows
interrupts that are generated by the corresponding pin to be sent to the interrupt controller on the
combined interrupt signal. Clearing a bit prevents an interrupt on the corresponding pin from being
sent to the interrupt controller. All bits are cleared by a reset.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
