The serial ports can be polled or interrupt-driven.
A polling driver tests the ready flags (TDRE and RDRF) until a ready
condition appears (transmitter data register empty or receiver data register
full). If an error condition occurs on receive, the routine must clear the
error flags and take appropriate action, if any. If the
flow control, transmission of data is automatically stopped when
goes high because the TDRE flag is disabled. This prevents the driver from
transmitting more characters because it thinks the transmitter is not ready.
The transmitter will still function with
because TDRE is not available to synchronize loading the data register
(TDR) properly.
An interrupt-driven port works as follows. The program enables the
receiver interrupt as long as it wants to receive characters. The transmitter
interrupt is enabled only while characters are waiting in the output buffer.
When an interrupt occurs, the interrupt routine must determine the cause:
receiver data register full, transmitter data register empty, receiver error, or
/DCD0
triggered. Another interrupt will occur immediately if interrupts are re-
enabled without disabling the condition causing the interrupt. The signal
