N-1
byte N
The Auto-CTS function is enabled by setting the CTSen bit. If Auto-CTS is enabled, the
transmitter circuitry in the U0TSR module checks CTS input before sending the next data
byte. When CTS is active (low), the transmitter 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. In Auto-CTS mode, a change of the CTS
signal does not trigger a modem status interrupt unless the CTS Interrupt Enable bit is set,
Delta CTS bit in the U0MSR will be set though.
generating a Modem Status interrupt.
Table 197. Modem status interrupt generation
The auto-CTS function reduces interrupts to the host system. When flow control is
enabled, a CTS state change does 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 can result.
