VLYNQ 2.X Packets
A command, length, address, and start receive data from the idle stream. A flow enable was received for the command channel, but there is data to return, so the flow is followed by a channel 1 descriptor the command for return data actually indicates a channel 1, and the channel 1 packet is now under way. A flow is now received for channel 1, but it is soon disabled so the channel 1 packet continues. The flow is enabled for channel one again, quickly after flow is released for channel 0, so the data continues for channel 0 when a flow is received again for channel 0. Channel 0 then receives a flow disable, completes its packet, followed by channel 1 flow disable, where the channel 1 packet is also completed
