#### Limitations
There is only one interrupt pin on the XBEE headers. This means that interrupt
pins DIO0 and DIO1 from the LoRa Bee are multiplexed through an OR gate.
This has the following limitations:
- FSK mode is not possible
- The interrupt pins can have different configurations, so caution is required
when making changes.
