5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
6.5.1 Interrupt mode operation
In interrupt mode (if any bit of IER[3:0] is 1) the processor is informed of the status of the
receiver and transmitter by an interrupt signal, INTA/INTB. Therefore, it is not necessary
to continuously poll the Line Status Register (LSR) to see if any interrupt needs to be
serviced. Figure 8 shows interrupt mode operation.
6.5.2 Polled mode operation
In polled mode (IER[3:0] = 0000) the status of the receiver and transmitter can be
checked by polling the Line Status Register (LSR). This mode is an alternative to the FIFO
interrupt mode of operation where the status of the receiver and transmitter is
automatically known by means of interrupts sent to the CPU. Figure 9 shows FIFO polled
mode operation.
