6.3.2
Auto-CTS (see Figure 5)
The transmitter circuitry checks CTS before sending the next data byte. When CTS is
active, it sends the next byte. To stop the transmitter from sending the following byte,
CTS must be released before the middle of the last stop bit that is currently being
sent (see Figure 6). The auto-CTS function reduces interrupts to the host system.
When ow control is enabled, CTS level changes do not trigger host interrupts
because the device automatically controls its own transmitter. Without auto-CTS, the
transmitter sends any data present in the transmit FIFO and a receiver overrun error
may result.
6.3.3
Enabling autoow control and auto-CTS
Autoow control is enabled by setting Enhanced Feature register bits 6 and 7
(autoow enable or AFE) to a ‘1’.
6.3.4
Auto-CTS and auto-RTS functional timing
The receiver FIFO trigger level can be set to 1, 4, 8, or 14 bytes. These are described
(1) When CTS is LOW, the transmitter keeps sending serial data out.
(2) If CTS goes HIGH before the middle of the last stop bit of the current byte, the transmitter nishes sending the current byte,
but is does not send the next byte.
(3) When CTS goes from HIGH to LOW, the transmitter begins sending data again.

(1) N = RCV FIFO trigger level (1, 4, or 8 bytes).
(2) The two blocks in dashed lines cover the case where an additional byte is sent as described in the preceding auto-RTS
section.
