I'm not sure I understand this question. > Are operations sent down in bulk, or one at a time? You can send as many as will fit in the payload. Unless you doing something like hopping, I suspect that command packets are relatively infrequent. > Will the RX chain simply start and return 504-byte length packets > until the next TX timestamp is sent down? I think this depends on how everything is configured. I think you'll have to do something (set some register) to enable the Rx at all. Likewise for Tx. As to how the Rx and Tx interact, I think that's still to be worked out. The right answer may depend on the application. E.g., a half-duplex "push to talk" radio (simplex or trunked) would probably run the Rx all the time, except when it was transmitting. A packet based radio may run some power measurement / RSSI code in the FPGA and only return Rx data when it wasn't transmitting and the power exceeded some threshold. > Could this starve the USB bandwidth?
