Registers (0x1C) and (0x1D) are reserved.
Register (0x1E) contains the data source definition for those interrupts with selectable data
source. Default value of each data source selection bit is ´0´.
Register (0x1F) is reserved.
Register (0x20) contains the behavioural configuration (electrical behaviour) of the interrupt
pins. Default value of (0x20) int1_od and (0x20) int2_od is ´0´. Default value of (0x20) int1_lvl
and (0x20) int2_lvl is ´1´.
