Configuration of Interrupt Inputs

The CPUs PM55x and PM56x provide 4 Onboard Interrupt Inputs. For using the interrupt functionality, the channels I0…I3 have to be configured accordingly.

In the channel parameters of Onboard I/O / Digital Inputs, the channels I0…I3 can be specified as interrupt inputs. 2 interrupt values can be chosen for each channel:

• Interrupt on rising edge
• Interrupt falling edge

The interrupt mode can be selected in parameter Input X, fast counter of the parameters list:

The configuration of the Onboard Interrupt inputs is now completed.
