/* ucc_slow_poll_transmitter_now

 * Immediately forces a poll of the transmitter for data to be sent.

 * Typically, the hardware performs a periodic poll for data that the

 * transmit routine has set up to be transmitted. In cases where

 * this polling cycle is not soon enough, this optional routine can

 * be invoked to force a poll right away, instead. Proper use for

 * each transmission for which this functionality is desired is to

 * call the transmit routine and then this routine right after.
