This double-type output has the same width as the "Channel vector parameter", where each element returns the number of missed interrupts. A missed interrupt is only detected when repetitions are created. This port is only active when the "Show missed interrupt output" option is checked.

This double-type output has the same width as the "Channel vector parameter", where each element returns the timestamp of the last interrupt received. This port is only active when the "Show timestamp output" option is checked.

This parameter associates a code module block with a configurable I/O module setup block. Set this value to match the Module ID defined in the setup block of the required configurable I/O module.

A vector of channels this driver block entity will access. You can specify channels in the range 1-N (N = the number of channels implemented in your specific configuration file defined in the Setup block). The width of this vector also defines the subsequent size of some of the following parameters if scalar expansion applies. With a single block, all the channels of the block are synchronized.

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.

Defines the source for interrupts. There are two possibilities:

When "FPGA input pin" is selected, there are multiple settings available to adjust the behavior of the interrupt input.

When "internally generated" is selected, the only setting available is the Interrupt frequency

This setting defines whether the rising edge (value 0), the falling edge (value 1) or both transitions (value 2) of the input signal are recognized as events.

A vector* of debounce durations in seconds. Defines the debouncing time. After the first registered transition, all following transitions will be ignored, until the debounce duration is reached. To turn off debouncing, enter the value 0. Range: from 0 to 57 seconds.

A vector* of delay values in seconds. Defines the time that the debounced signal is delayed before the interrupt is asserted. During the delay, new interrupts are ignored, but the flag counter is incremented. To turn off the delay, enter the value 0. Range: from 0 to 57 seconds.

This checkbox enables the advanced settings for the interrupt input. A threshold or a number of repetitions can be defined.

A vector* of interrupt event thresholds. Defines the number of interrupts to reach, before one interrupt is propagated. The threshold operation is executed after the delay and before the generation of repetitions. To turn off the threshold, enter the value 0. This parameter is only visible when Advanced settings are enabled.

A vector* of interrupt repetitions. Defines the number of repetitions for one interrupt. The time between the repetitions is defined in the "Time gap vector" -dialog field. During the repetitions, new interrupts are ignored, but the flag counter is incremented. The repetitions are generated after the threshold operation. To turn off repetitions, enter the value 0. This parameter is only visible when Advanced settings are enabled.

A vector* of time between the repetitions. Defines the time gap between the repetitions. Range: from 13.3ns to 57 seconds. This parameter is only visible when Advanced settings are enabled.

A vector* of frequencies. Defines the frequency of occurring interrupts. The smallest step width depends on the FPGA frequency; for example, when the FPGA frequency is 75MHz, the smallest change between two period times is 13.3ns. The precise computed time in seconds appears next to the Interrupt frequency parameter. This parameter is only visible when the interrupt source is "internally generated".

Enables the timestamp output port to read the timestamp of the latest interrupt. The timestamp is a 64-bit counter value on the FPGA which starts to count when the model is started.

Enables the Flag output port to read the number of missed interrupts.
