When a break condition occurs, TX is pulled low. A break condition is activated by setting the UART_LCR[6] BREAK_EN bit. The break condition is not aligned on word stream (a break condition can occur in the middle of a character). The only way to send a break condition on a full character is:
The break condition is asserted while the BREAK_EN bit is set to 1.
The time-out counter and break condition apply only to UART modem operation and not to IrDA/CIR mode operation.
