Fifth Interrupt Register
Offset: 27h
Please be aware that writing to this register will enable/disable the corresponding
interrupts, while with reading you get the actual interrupt status and will clear the
register at the same time. It is not possible to read back the interrupt enable/disable
settings. This register is reset at a DVDD-POR.
