The SimpleLink device can send a message to the host at any given time. The SimpleLink host protocol does not allow data loss. When the host enters into a low power mode, it must raise the RTS line to signal the SimpleLink device that it cannot receive data.
However, when RTS line is raised, the SimpleLink device is not able to wake up the host. In this case, to allow the host to wake up by the SimpleLink device, the auxiliary HOST_IRQ line should be used.
