Time Out Interrupt Flag (Read Only)
This bit is set when the RX FIFO is not empty and no activities occurred in the RX
FIFO and the time out counter equal to TOIC. If UA_IER [TOUT_IEN] is enabled, the
Tout interrupt will be generated.
NOTE: This bit is read only and user can read UA_RBR (RX is in active) to clear it.
