In case both IRQ modes (Modus_1 and Modus_2) are set for one channel, this channel
reacts according to the OR logic and is linked with the other inputs through an AND logic.

Fig. 8-8: OR and AND logic combination by AND logic

Modus_1 and Modus_2 are set to 1 for the channel 0/4. It reacts either to Low or to
High level (OR logic).
To generate an interrupt, the former condition and the condition set on channel 1/5
(High level) are to be fulfilled (AND logic).
The AND and OR logics are the same when both modes are activated on all selected
interruptible inputs.
