TouCAN Interrupt Generator

Generate an interrupt subsystem for CAN interrupt sources

Embedded Target for Motorola MPC555

Description

The TouCAN Interrupt Generator block generates a function-call trigger within a TouCAN interrupt and executes a callback in the context of the interrupt service routine.

This block may be used to execute a callback on occurrence of Bus Off, Error, or Wake interrupts.

Do not use this block unless you are aware of the dangers of using asynchronous interrupts in the model. Unpredictable data loss or model behavior may result unless extreme caution is taken.

For faster interrupts, you can disable floating point support via the Use floating point option. However, if you disable floating point support, do not use blocks that require floating point operations in your model. Use of such blocks will cause a floating point exception at runtime.
