7.2.2 Auto-CTS
Figure 6 shows CTS functional timing. The transmitter circuitry checks CTS before
sending the next data character. When CTS is active, the transmitter sends the next
character. To stop the transmitter from sending the following character, CTS must be
de-asserted before the middle of the last stop bit that is currently being sent. The
Auto-CTS function reduces interrupts to the host system. When flow 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.
7.3 Software flow control
Software flow control is enabled through the Enhanced Features Register and the Modem
Control Register. Different combinations of software flow control can be enabled by setting
different combinations of EFR[3:0]. Table 3 shows software flow control options.
(1) When CTS is LOW, the transmitter keeps sending serial data out.
(2) When CTS goes HIGH before the middle of the last stop bit of the current character, the transmitter finishes sending the current
character, but it does not send the next character.
(3) When CTS goes from HIGH to LOW, the transmitter begins sending data again.
