9.3.11 Polled Mode Operation

In polled mode (IER[3:0] = 0000), the status of the receiver and transmitter can then be checked by polling the

line status register (LSR). This mode is an alternative to the interrupt mode of operation where the status of the

receiver and transmitter is automatically known by means of interrupts sent to the CPU. Figure 25 shows polled

mode operation.

9.3.12 Break and Timeout Conditions

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].
