PRODUCTION DATA.
An RX timeout condition is detected when the receiver line, RX, has been high for a time equivalent to (4 × programmed word length) + 12 bits and there is at least one byte stored in the RX FIFO.
When a break condition occurs, the TX line is pulled low. A break condition is activated by setting LCR[6].
