5 V, 3.3 V and 2.5 V UART with 16-byte FIFOs
6.3.3
Enabling autoflow control and auto-CTS
Autoflow control is enabled by setting MCR[5] and MCR[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 in
Figure 8
and
Figure 9
.

(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 finishes sending the current byte, but
it does not send the next byte.
(3) When CTS goes from HIGH to LOW, the transmitter begins sending data again.

(1) N = RX 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
