It shouldn't be called from within atomic blocks or interrupt handlers since it re-enables interrupt flag on exit or even hangs in infinite loop waiting for execution of UDRE interrupt. In MPCM mode first received byte is address by which device was called own or general callapplication is also responsible of restoring into "idle listening" state withing described bus silence time after receiving entire packet. Pin used as a RS control line have to be kept in low state during boot process via a pulldown resistor or at least not driving it high even by an internall pull-up. In half duplex RS transmission modes, the application code is responsible of starting transmission only when bus is idle. Any used IO pin have to be accessible from bottom IO address space. Designed especially for real-time or high throughput applications, with narrow resource limits. If nothing happens, download the GitHub extension for Visual Studio and try again.
