Single UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR

7.2.1 Auto RTS

Figure 9 shows RTS functional timing. The receiver FIFO trigger levels used in auto RTS

are stored in the TCR or FCR. 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 deasserted.

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 deassertion 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 reassertion allows the sending

device to resume transmission.
