Figure 1. Autoflow Control (Auto-RTS and Auto-CTS) Example
auto-RTS (see Figure 1)
Auto-RTS data-flow control originates in the receiver timing and control block (see functional block diagram)
and is linked to the programmed receiver-FIFO trigger level. When the receiver-FIFO level reaches a trigger
level of 1, 4, or 8 (see Figure 3), RTSx is deasserted. With trigger levels of 1, 4, and 8, the sending UART may
send an additional byte after the trigger level is reached (assuming the sending UART has another byte to send)
because it may not recognize the deassertion of RTSx until after it has begun sending the additional byte. RTSx
is automatically reasserted once the receiver (RCV) FIFO is emptied by reading the receiver buffer
register(RBR).
If the trigger level is 14 (see Figure 6), RTSx is deasserted after the first data bit of the sixteenth character is
present on the SINx line. RTSx is reasserted when the RCV FIFO has at least one available byte space.
auto-CTS (see Figure 1)
The transmitter circuitry checks CTSx before sending the next data byte. When CTSx is active, it sends the next
byte. To stop the transmitter from sending the following byte, CTSx must be released before the middle of the
last stop bit that is currently being sent (see Figure 2). The auto-CTS function reduces interrupts to the host
system. When flow control is enabled, the CTSx 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.
enabling autoflow control and auto-CTS
Autoflow control is enabled by setting modem-control register (MCR) bit 5 (autoflow enable or AFE) and bit 1
(RTS) to 1. Autoflow incorporates both auto-RTS and auto-CTS. When only auto-CTS is desired, bit 1 in the
MCR should be reset to 0 (this assumes a control signal is driving CTSx).

NOTE A: When CTSx is low, the transmitter keeps sending serial data out. When CTSx 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. When CTSx goes from high to low, the transmitter
begins sending data again.
