7.2.1 Auto-RTS
Figure 5 shows RTS functional timing. The receiver FIFO trigger levels used in Auto-RTS
are stored in the TCR. RTS is active if the RX FIFO level is below the halt trigger level in
TCR[3:0]. When the receiver FIFO halt trigger level is reached, RTS is de-asserted. The
sending device (for example, another UART) may send an additional character after the
trigger level is reached (assuming the sending UART has another character to send)
because it may not recognize the de-assertion of RTS until it has begun sending the
additional character. RTS is automatically reasserted once the receiver FIFO reaches the
resume trigger level programmed via TCR[7:4]. This re-assertion allows the sending
device to resume transmission.
