Purpose of the AIFXv2 mode

With the release of netX Studio CDT V1.0700.1.3056, Hilscher introduced the AIFXv2 mode that enables users to create one hardware configuration (HWC) file for real-time Ethernet and Fieldbus loadable firmware (LFW) versions. As illustrated in Figure 1, instead of creating a HWC file with either a real-time Ethernet or Fieldbus network interface, the AIFXv2 mode enables both pinout options selectable by using specific configuration input pins as summarized in Table 1.

The selection of the network interface in the AIFXv2 mode is determined by the voltage level at the configuration input pins XM0_IO1, COM_IO1 and COM_IO0 during the boot sequence of the chip. The pull-down resistor of each configuration input pin is enabled by default after reset. If the pins are left unconnected, the default mode is real-time Ethernet.

Please note that the AIFXv2 mode is passed on from the HWC to the LFW in order to verify whether the selected network interface and programmed LFW version do match.
