Description

When you add the Software Interrupt Trigger block to a model, the block polls the values on the input port. When the input value is greater than the value in the Trigger software interrupt when input value is greater than parameter, the block posts the interrupt corresponding to the selected CPU and Peripheral Interrupt Expansion (PIE) numbers to the Hardware Interrupt block in the model.

To use this block, add a Hardware Interrupt block to your model. The Hardware Interrupt block processes the software-triggered interrupt from this block into an interrupt service routine on the processor. Set the interrupt number in the Hardware Interrupt block to the value you set in the Software Interrupt Trigger block.

The CPU and PIE interrupt numbers together specify a single interrupt for a single peripheral module. For information about the mapping of CPU and PIE interrupt numbers to these peripheral interrupts, see C28x Hardware Interrupt.

Note

Fixed-point inputs are not supported by the Software Interrupt Trigger block.

Ports

Input

PIEIFRx.INTy — Triggers software interrupt

scalar

The Software Interrupt Trigger block triggers the software interrupt based on the CUP interrupt number and PIE interrupt number parameters when the input value is greater than the value in the Trigger software interrupt when input value is greater than parameter.

Data Types: int8 | uint8 | int16 | uint16 | int32 | uint32 | single | double | Boolean

Parameters

CPU interrupt number — CPU interrupt number corresponding to hardware interrupt

7 (default) | scalar

Enter an integer value to set the CPU interrupt number corresponding to the hardware interrupt. For information about CPU numbers of C2000 processors, see C28x Hardware Interrupt.

PIE interrupt number — PIE interrupt number corresponding to hardware interrupt

8 (default) | scalar

Enter an integer value to set the PIE number corresponding to the hardware interrupt. For information about PIE numbers of C2000 processors, see C28x Hardware Interrupt.

Trigger software interrupt when input value is greater than — Sets value above which block posts an interrupt

0 (default) | scalar

Enter the value for the level that indicates that the interrupt is asserted by a requesting routine.
