* An event can be generated for each port. The first event is related to the

* An interrupt is generated when one or both events have occurred.
*
* data[0] Number of the input port on which the event will take place (1 or 2)
* data[1] The event logic for port 1 has three possibilities:
* APCI1500_AND This logic links the inputs with an AND logic.
* APCI1500_OR This logic links the inputs with a OR logic.
* APCI1500_OR_PRIORITY This logic links the inputs with a priority OR
* logic. Input 1 has the highest priority level
* and input 8 the smallest.
* For the second port the user has 1 possibility:
* APCI1500_OR This logic links the inputs with a polarity OR logic
* data[2] These 8-character word for port1 and 6-character word for port 2
* give the mask of the event. Each place gives the state of the input
* channels and can have one of these six characters
* 0 This input must be on 0
* 1 This input must be on 1
* 2 This input reacts to a falling edge
* 3 This input reacts to a rising edge
* 4 This input reacts to both edges
* 5 This input is not used for event
